Very nice acquisition and a bargain to boot.
You may find the following of interest:
FRAME STAMPINGS - SERIAL #s/REFINISH/REWORK/OTHER:
(Note: Almost any statements about S&Ws are presumed to be trends, and should not be taken as rules.)
Serial # Locations & B or N stamps:
Always use optical magnification including a flashlight when looking at or for serial numbers to observe the information accurately.
Pre war fixed sighted guns have serial #s in 6* locations, target** models as many as 9*. Triple Locks have 7 including the mid lock cam plate, making it 10 locations on Target models.
*Post War continued the 6 and 9 (early Transitional target models with pre war sights only) s/n locations on fixed sight/target models with pre war sights until 1956-57, but dropped the 3 target sight locations post war on the new Micro-click sighted models, which were no longer specifically fitted to the top strap.
**Target models will have the serial number on the front sight, under rear sight, and the rear sight blade although sometimes not, and sometimes #'d with assembly (factory work) # instead of serial #. If the s/n is more than 4 digits, the front and rear sight blades can have a partial s/n. All three parts must be removed to observe the #s. Non-numbered front and rear sight blades have typically been replaced, in most observations.
We owe the Russians a vote of thanks; having been the 1st to require multi-serial # locations on their S&W #3 contract revolvers.
Here are the 6 (or 7 on Triple Locks) fixed sight frame serial # locations pre war and locations remaining after WW II until 1957 to look for (not including pre war target sight stamped serial #s):
Here are the 6 fixed sight frame serial # locations for your model.
NOTE: Observing serial #s for accuracy or even existence, especially on penciled stocks, requires magnification, bright light, and an attitude that it’s there!
Gun butt* - or forestrap* on I frames with grips that cover the butt
Barrel - bottom of barrel or in extractor shroud
Yoke - on rear face visible thru a chamber with a flashlight
Extractor star - backside
Cylinder - rear face
Right stock only** - on back; stamped, scratched or penciled depending on vintage and stock material.
Mid-lock cam plate – “.44 HE 1st Model - Triple Locks” only, in any caliber (up to all 5 digits).
*NOTE: The one TRUE place you can be sure of reading the original serial number for all Hand Ejectors of any vintage, (which includes any letter prefixes after WW II,) is the BUTT of the gun, (or Front grip strap on non-round butt .22/32 Kit guns and Targets and .32 & .38 S&W Regulation Police pre Model of 1953 I frames). The number on the butt may be drilled thru by the factory for installation of a lanyard swivel but is re-stamped on the grip frame, under the left stock. Factory installed swivels are always 1/10” forward of center. Generally the Pre war serial # on the butt reads with barrel to the right including I frame serial numbers on the forestrap. After WW II it reads with barrel to the left except for serial numbers on the forestrap.
** Stamped since 1857, stock #s, always right side only, changed to penciled #s c. 1900 and back to stamped #s in 1929. Scratched, penciled or stamped on hard rubber and premium stocks; numbering discontinued ~ late 1970s.
Decreasing Serial # locations began May 1, 1957 when S&W eliminated the Soft Fitting Operation. They stopped routinely stamping the serial number on the barrel, cylinder & yoke arm over a transition period. Serial # locations dropped from 6 locations to only 3; butt, back of right stock (until mid '70s), and extractor star (until c. 1980). So guns in process or in inventory as of 5/1/57 can still have more than 3 and up to 6 locations and guns shipped after this time will have the former number locations because assembly was done in advance and inventory using the old process had to be used up.
Eventually down to only 3 serial # locations left by c. late 1957 which are:
Gun butt
Extractor star - backside until ~ 1980 with the new extractor star shape.
Right stock – backside until ~ 1979 when stocks were no longer hand fitted.
Once laser engraved serial numbers were introduced, the last two locations continue on the bottom of the butt and in the yoke cut. But there are exceptions, like below the cylinder, left side of frame below the cyl window and may or may not be on the butt.
Assembly (factory work) #s: Other multi-digit numbers of 3 to 5 digits, are on the yoke at the hinge, in the ‘yoke cut’ on frame opposite the yoke near the hinge, and inside of the sideplate, for the pre war and early post war period. The assembly # in the yoke cut of the frame was relocated to the left side of grip frame after model #s were assigned and the serial # was added in the ‘yoke cut’ where the assembly #, moved to the grip frame, used to be. You know they are assembly (factory work) #s because of those 3 locations that always match on guns that are original, and that’s the only usefulness for them after guns leave the factory: still used to this day, long after serial number locations decreased.
*EXCEPTION: see rear target sight blade numbering under serial # locations above.
Serial number and assembly # locations have more changes soon after 1957 and get more confusing. When Model Number stamping began not long after being ordered June 12, 1957, the serial number was not yet stamped in the frame ‘yoke cut’ on the frame side of the yoke hinge until late 1959 and early 1960. Then the serial # was only stamped in the frame ‘yoke cut’ when the revolver model was shipped with target stocks as standard. But soon after, serial #s were stamped on the frame in the 'yoke cut' on all models, except on some smaller guns at first where it just didn't fit well. But when serial #s were stamped on the frame in the ‘yoke cut’, the frame assembly # from the 'yoke cut' was moved to the left side of the grip frame. The 3 assembly # locations, on yoke, left side of grip frame and backside of side plate remain to this day.
“The reason for the triple alpha-numeric serial number system is that S&W ran out of serial numbers that they had been using up to the 1980 and need a serial number series that had enough number possibilities to keep them going for many years. The first guns in the triple alpha four numeric series was the L frame revolvers starting AAA0001 in 1980. The rest of the models were slow phased in from 1980 to approximate 1983. When it came time to assign the new series to the auto-loading handguns they were started at TAA0001. After this the company jumped around in the new series depending if there was a demand for a special number. I actually have three guns serial numbered RGJ0001 - 0003 and they are all different models. ATF objected to the company assigning special numbers and so now they are in a little better order. I hope that this answers your question.” Roy
NOTE: 'B' or 'N' stamp: ahead of pre war serial #s on the barrel flat (or in shroud), rear face of yoke, on rear face of cyl by itself, behind the extractor star, and by itself on right side grip frame on commercial guns (only on left side grip frame on post war models) indicates an original Blue finish or for an original Nickel finish based upon the corresponding letter. The occasional absence of either the 'B' or 'N' can indicate that it left the factory nickeled. Also there was a larger B behind the barrel serial # for the Bright blue optional finish in the post war era - early ‘50s when satin blue was standard. “I've seen nickel Triple Locks with N stamps. I've seen them without it, too. Pre-war guns MAY have an N, or they may simply lack B's.” Regards, Lee Jarrett
The post war and the 1950s period, was one of much evolution. There was the usual transition when finish code letter stamps were dropped and frame code letter s/n prefixes began, when there were neither letter stamps on major parts (except the butt).
Caliber code single digit number stamped on grip frame: N frames. The normal side for the cal. code # is the left side.
357 Mag no number code observed
38 special will have an 8
44 special has a 4
44 Mag has a 0
45 ACP has a 5
45 colt should have a number 7 on either side of the grip frame (convertibles stamped E5 & E7)
Misc. single digit letter or number: stamps in yoke and cylinder and/or grip frame either side are fitter stamps and inspector stamps in general. An L on front face of cylinder of post 1960 models indicates left hand threaded extractor rod.
Star by the serial #: On the bottom of the butt or left side of grip frame indicates a factory rework; began~ 1910, declined in the early 1960s along with date stamps.
Deviations: Roy Jinks once said that the star wasn't always used (earliest known 1926 and star was on several parts). A nickel .32 RP that was built pre-war went back post war and got a new barrel, cylinder and re-finish; It is not marked by the SN, but does have stars on the barrel, cylinder and yoke.
A New Model Number 3 target that was completely redone by the factory in June of 1956 doesn't have a star. A .32-20 re-finished in the early 1970's did get a star stamp. Also, the star was not always put on the butt by the serial number. If you didn't want the star stamp on the butt, the factory would stamp it on the grip frame under the grips, which fits with a few guns we've seen with the star on the grip frame.
Refinish/Rework Dates: after 1910 for a return to the factory are 3 or 4 digits depending on the actual date (sometimes 5 or 6) placed on left side of grip frame on the 'toe' stamped vertically or horizontally, and will not match any other stamped #s on the gun. Ex: 3.48 for March 1948, 10.2.57 for Oct 2, 1957, etc.
Sometimes letters in a rectangle or diamond, B (blue), N (nickel), or S (standard/blue) with an R (for refinish), on 'heel' of left side of grip frame. There might also be marks in diamonds like <S> (silver), <G> (gold), or a P (plated) with a circle. In the 1960s period, an S<> on grip frame and under barrel with a rework date meant refinish, standard (blue). Which stamping was used depended on the time frame and service technician working on the gun.
Refinish and date stamp usage is generally accepted to have declined in the early 1960s and was eventually eliminated altogether not too long after. Reportedly none have been observed since 1983.
