Unidentified Colt SAA Clone

Sorry I didn't get the pictures of the internals up but it's kinda busy for me this period of the year but they're coming hopefully tomorrow ...

Internals

Pictures are not very sharp that's why I didn't resize them so the details remain visible. As you can see the bolt is lifted up by a little piece. The main spring is in two parts (maybe a home made replacement ?) and so is the sear bolt spring. The hammer is different of a normal saa too there is some kind of extra lever with a spring that comes up and down.

Last pic the bolt (top) and the piece that lifts it up ...
As you can see (or so I hope..) the hammer has no cam. There's a kind of small lever with a spring on the side of the hammer that moves the bolt I guess...

FWIW, I have never seen an SA mechanism like that. I still think the gun might be a prototype, but I confess I don't see quite how it works or what the advantage would be over the regular (Colt) SA lockwork.

I think I see how it works. The rectangular piece, rounded on top is the bolt (cylinder stop). It moves up and down, possibly in a slot in the frame.

The sort of V shaped part pivots on the same pin as the trigger and is powered by the curved spring. As the hammer is cocked, a cam on its front moves the back end of the part up, causing the front part to move down and pull the bolt down with it, freeing the cylinder to turn. At some point, the cam releases the V part and the spring pushes it and the bolt back up to stop and lock the cylinder.

Assuming it works (whether that way or not), it would eliminate the split cylinder stop, a weak point in the Colt design, and the double spring. The problems are that it would substitute two springs for one, not really a better idea, and require fairly close tolerances in the camming action, closer than those needed in the original design.

Again assuming that my analysis is correct, the new parts would be easier to make and (probably) require less fitting, But it would increase the number of parts and I do not believe it would make the revolver more reliable.

Still, it is an interesting variation and obviously required a good deal of thought and careful workmanship. Had it come along 150 years ago, it might have had some influence, but the current SAA design is pretty much cast in concrete at this point, and Ruger has a lock on an improved and simplified design. I can't see any future for it.

If the OP has the time, one research approach might be a patent search to see if the idea was ever patented.

Jim, I think your right about function. That's what I had surmised (a la D.A. style but hammer actuated) but wanted a better view of the actual parts. I also agree, it's a weaker set up. It would suffer lateraly (was wondering how a bolt block would fit against it) for sure. Bill did a nice job "re inventing " the actuation of S.A. parts!!

I think one thing is for sure - there weren't 22,422 of them, so either old parts were used or someone just made up a serial number. Could the gun originally have been a Colt? Maybe, but that determination would require a lot more information and probably doesn't matter anyway.

Hello everybody.

Thanks for all the replies. And first I'll try to get a better set of pictures of the internals.
James K , you resumed very well how this particular gun works. Your description is actually spot on.
I don't believe the serial is correct either and also think it was either added later on or that the revolver in question was some kind of prototype...
The way it works got me totally puzzled. I bought it because it looked good and because it was nothing like any other single action revolver I've seen so far. I do believe it's quite an old gun seeing as the genuine stag grips seem quite old and where made to fit this revolver perfectly.

I'll be posting some better pictures of the internals very soon and will try my luck at SASS to see if someone has seen a similar SA revolver with this particular mechanism.

Again thanks for your interest in the topic.
