Good day to all. New member and first time poster. I have had this revolver as a safe queen for some time and was wondering more the value than the history as I have already gleamed alot of info off this site regarding these specific revolvers.

It is a model 1917 hand ejector five screw that has been remanufactured to the 455. The butt has the lanyard ring still attached and the frame is stamped "U.S. ARMY MODEL 1917. The serial number below that is "No 701**". The ejection rod fits under the barrell and is not shrouded. There is no sign of any markings on either side of the cylinder face. To the rear of the cylinder though is stamped a crown and underneath "BNP" six times. One for each flute of the cylinder. The left side of the barrel is stamped "S&W D.A. 45". Above that is what appears to be an overstamp of ".455 .760 TDNS FER and a square box". Also there is a crown stamped into the barrel and "BNP". There are no markings on the right side of the barrel. The top of the barrel is stamped in two rows the lenght of the barrel "SMITH & WESSON SPRINGFIELD MASS USA" then "PATENTED DEC. 17 1901 FEB. 6 1906 SER 14909". On the bottolm of the barrel is "UNITED STATES PROPERTY"
On the left side of the frame next to the yoke is ".455 MK VI". I believe it has the original wood grips with no markings on them. There are various other markings overstamped onto the revolver but I have only included the ones I think are most noted. The weapon is in fair (given it's age) to poor condition. The blueing has developed a pateena to it and the cylinder is fairly loose as it fits on the yoke. Any and all info will be greatly appreciated. I can probably manage photos, if I can figure out how to load them onto the site. Thanks again.

At least to my knowledge, there were many British .455 revolvers which were converted to other calibers, but I have not heard of a Model 1917 (.45 ACP) being converted to .455. But that does not mean it couldn't have happened.. About the only way that could have been done is by cylinder replacement. Does the SN stamped on the rear face of the cylinder match those in the usual other SN locations?
 
Cylinder Stamping Question

There are no numbers stamped on either end of the cylinder face. The only thing I can find is a "D" stamped on the rear of the cylinder face underneath the ejector star. Hope that helps.
 
The ' .455 .760 TDNS FER and a square box" is the caliber (.455), .760 is the case length in inches.
'Tons Per Square Inch' should have a number along with it to indicate the Service pressure of the cartridge.
The 'ton' is the English 'Long Ton' measurment. I forget what it's equivilent ,,1250psi or something like that. Google can tell you.
The above is a post 1954 proof marking (English)

Crown/BNP is Birmingham (English Proof House) Nitro Proof. It's probably inside of a boldly stamped circle. The circle denotes an arm not of English mfg.
These could be earlier marks than the first set.,,pre WW2 perhaps. IIRC, they started using them in 1925.

The .455 Mk VI is a caliber designation for the converted revolver.
.455 Webley Revolver Mark 6 Round.
A full metal jacketed bullet round that came about around 1938/39 IIRC to satisfy the War Conventions demands that outlawed lead and expanding nose bullets.

The 455 Webley rounds have a very thin rim compared to the original 45 Auto Rim cartridge that the 1917 S&W was made for. They will fit and fire but are grossly excess headspaced.
As DWalt points out,,a new cylinder in .455 would be fitted to fix that problem.
With no ser# or other markings on the rear of the cyl, that may be what they did if they had extra/surplus .455 cal cylinders at hand.
 
Thank you for the information. It helps me understand more the history of this weapon. Keeping in mind it is in fair to poor condition in regards to blueing can you give me a ballpark value?

Thanks again to all.
 
Asking for an value estimate without photos is like asking someone to put a value on your automobile without letting them go into the garage.
 
Last week there was a thread titled 'Curious Bird' which has has been deleted for some reason.

It was about a 1917 Army 45 from WWI with a .455 barrel and cylinder. I intended to post a link to this old thread about a similar conversion for any members interested before the thread disappeared. Just another interesting example of S&W aftermarket conversions and likely not the only two.
 
I will cut through the chase a bit as a mix master, converted gun with mixed parts other than value as a utility gun shooter, not much. If your typical US model 1917 in similar condition is going for say 800 bucks cut the value in HALF. So roughly $400

I saw that post. I also saw one similar to it, but it did not quite match the description, and some wear. From my notes on the one I saw:​

  • Stamped vertically U.S. ARMY 1917 on one side of the lanyard loop, and a star and serial number on the other side.
  • On the left side of the barrel, SMITH & WESSON .455 in the same font.
  • Right side, my notes say nothing.
  • 5-digit s/n.
  • Serial numbers on butt frame, barrel, and cylinder all matched, and very clear.
  • A "B" inside a diamond on the barrel flat.
  • NO British proofs, or war-time inspector stamps anywhere on that one, NO Canadian stamps, nothing. I looked very carefully.
  • Card on table with the gun read "Model 1917, 45 Long Colt, No ACP, factory reblued, S+W (not) original grips.
If the one I saw was a reblued gun, it was a very nice reblue, just a little worn. I am not an expert on these, and it did not seem to fit into anything I saw in the SCSW.
