What's my barrel length on this Reg. Magnum?

I've been measuring revolver barrels for some time now and have found that many are under what is advertised by as much as 3/16". Usually it's 1/8" to 1/16". This is true of pre-war revolvers as well. Sometimes they're at size or even a 1/16" over, but not often. The actual intended barrel length of my RM will only be decided by a S&W factory letter and nothing else I guess. I thank all for trying to help.

Do not forget to come back here when your letter arrives.;)
 
The OP received the factory letter but is having problems with posting it. He emailed a picture of the letter to me and asked that I post it for him. It is attached below. The gun was ordered and shipped as a 5-1/2" barrel, not as rare as a 5-1/4" barrel, but still not often seen…..

Jinks tells us the barrel length tolerance for RM's was +/- 1/16". Looks like this may have been a Friday afternoon or Monday morning gun--------unless of course the muzzle was boogered somewhere along the way, and repaired.

Having said all that tolerance talk, I can't imagine an RM passing inspection with an error of that magnitude. Possibility next is---while the order form says it ordered with a 5 1/2" barrel, who's to say the buyer didn't change his mind in mid-stream, and asked for 5 1/4"? (My last RM was ordered with service stocks with grip adapter attached. Then, shortly after the Magna grips came along, he changed his mind.) That's just one of the little tib-bits SWHF came up with on that gun. Sounds like a search order to SWHF is next on your agenda.

And as an aside, where does it say it was shipped with a 5 1/2" barrel?

Having been jarred into a state of semi-consciousness at this ungodly hour (for me!), I awoke thinking about the very odd protrusion of the barrel beyond the rib common to these guns. Then I stumbled to my desk to check the pictures, and damned if this gun doesn't still have it!

What that says to me, strictly as a matter of opinion, is this gun hasn't been messed with since it left Springfield-----at least not very likely by anyone except Springfield. So much for my "boogered" and repaired theory. UNLESS, that is, SWHF has something hidden away that tells us otherwise----damn it anyhow!

The shipping invoice lists REG. #1705 was shipped to Edward K. Tryon with a 5 1/2-inch barrel. Exactly as ordered by them on November 19, 1936. I can post a photo of it later today if that would help end speculation about barrel length.

What is a registered magnum? Is it a model pre numbers like 29-, 66- etc?
 
From its introduction in 1935 to late in 1939, each .357 Magnum ordered was assigned a registered number and the arm was put through the factory per the specifications of the customer. A certificate of ownership/permanent guarantee was sent to each owner of a Magnum upon return of a numbered card accompanying each arm. The registered number was stamped in the yoke cut. These .357 Magnums are referred to by collectors as Registered Magnums. The assigning of registered numbers was discontinued in late 1939. Magnums produced after this up to 1941 when production was stopped due to WW II are referred to as Nonregistered Magnums. The first .357 Magnum that could be considered a Pre-Model 27 was shipped in November 1949.

Well, there you have it! It doesn't really matter what it is. If the records say it's 5 1/2", that's what it is.

Yes, the letter does create some questions. I noticed also that it states that it was "shipped from our Roosevelt Avenue factory on December 18, 1936", yet that facility wasn't in operation until 1949. Obviously, that couldn't have been on the original Company records. I've sent an advanced research request. Maybe something else might turn up. The barrel muzzle seems normal to other original RM's I've seen and I see no evidence of any rework. I know if I spent the huge amount of $60 for a special order gun in 1936, I'd want it as requested.
 
The Magnum was shipped from S&W's plant on Stockbridge Street (letter is incorrect). See invoice below. There are four other documents concerning your .357 Magnum, namely, the order sent to S&W by Edward K. Tryon Co., Philadelphia, PA, for one .357 Magnum with a 5 1/2-inch barrel, the S&W order form filled out by company after the order was received, a letter to S&W from Frank Mitsch asking a new certificate be issued to Abe Hepner, Gary, IN the new owner of the Magnum, and the response from S&W stating a new certificate has been issued.

Bill, the REG number on the shipping invoice appears to be 1706, not 1705. Can you verify please.

Note: I have also asked the OP to verify the REG number on the gun and send me a picture of it.
