Anybody ever see a Smith & Wesson Revolver with an action that looks like this?

Yes. It could be a .38 M&P Model 1899 or Model 1902. Show more pictures of the whole gun.

Even easier, just give us the serial number and cartridge. It could be either a .38 Special or .32 Winchester (.32-20).

Wiregrass guy is correct, but these items will allow you to get more detailed information.

This gun is a "real" Smith & Wesson. The Spanish S&W copies have an action with a "V" mainspring similar to Colt D.A. revolvers instead of the flat spring that real S&Ws have.

Here is the OP's original picture, rotated just a little.



And here is a picture of an equally dirty lockwork of one of my guns, before I cleaned it. Focus on the hammer and trigger, and not the front of the trigger that pulls the cylinder stop down. This gun is a transition revolver, with the new cylinder stop, but the early original hammer and trigger return mechanism.



The hammer and trigger return mechanism are identical in the two pictures. The gun in question is not a Spanish copy, but an early S&W.

Not to mention identical placement of the chafing bushings. I don't recall ever seeing chafing bushings in a Spanish copy. Did any of the Spanish guns have them?

That is because neither OP's nor Mike Priwer's photos are of Spanish guns, they are both real S&Ws Maybe I mis-understood the purpose of your post.

If the gun is a Model 1902, I see a big difference in the cylinder stop. My 28,XXX and 61,XXX lock-works are shown below. The OP's interacts differently with the cylinder stop. The 1902 S&Ws have a small return pin that allows the stop to return and is reset by the trigger. So it can't be a 1902 or 1905, but the cylinder stop on an early 32 HE and looks like the OP's picture. My Model 1903 32 HE (bottom picture). Problem is that the early Model 1903s did not have the rocker type trigger return, but rather a long spring the ran down to the base of the butt-frame.

Bottom line is that I have a difficult time believing it can be a Model 1896, Model 1903, or a Model 1902, So where does this leave us with regards to the OP's gun???????? Was there an engineering change on the cylinder stop before the rebound slide? My 61,XXX gun was shipped in 1905, so does not seem likely that you would see a new cylinder stop before the rebound slide was started??

Gary,
Read Mike's post again. YES, the cylinder stop was changed before the rebound slide was added, but the pic showing that is Mike's gun:



THIS is the OP's gun. Note the cylinder stop is the early one that you show:

Thanks for your clarification.

Mike,
You're welcome. Is your gun a Round Butt or Square Butt?

So the revolver is actually a Model 1902 as Mike stated. I found the pin on the cylinder stop after I lightened the OP's photo. Was thinking the cylinder stop was flat indicating a Model 1905 No Change, but it was too dark to see the detent pin (my new glasses will arrive next week). Now I see it is not a Model 1905.

What about the 2nd pict in Cpt Bret post. Is the spring loaded detent very widespread in that age S&W? My prewar 38/44 OD has this feature.

Lee

The gun is a 4" blue round-butt 32-20, serial number 21110. Here are a couple pictures of the gun. It's had it's share of wear and tear, but all the parts number to the frame, except the grips. The sideplate is numbered to the work order number.

Yes for early K and N frames.

The new cylinder stop was started in 1905 and the rebound slide was introduced in 1906 on K frames. The N frames did not start production until 1908 and the 38/44 did not start until 1930, why weren't all N frames produced with a rebound slide and new style cylinder stop?

My two triplelock revolvers, both shipped in 1916, are 5-screw frames with the rebound slide. I would think that all N-frames had these features.
