My, my, you boys are excitable.

Slow down, and think a bit.
Knockoff.
KNOCKOFF.
First, look at the logo closely. Francois the engraver either did not have a logo close by, or he intentionally varied it, perhaps to avoid a Belgian prison for forgery. If you look closely, you will notice that we have a star very similar to an asterisk * at 3 and 9 o'clock. The S&W logo has diamonds in those spots. I have never seen or heard of stars.
BTW-
Why would they take time to put the logo and cyl engraving on a prototype if they did not even take time to put assembly numbers on it?
Don't the grips look amazingly like french walnut? They are not circassian, and I do not believe they are american. That's the two walnuts we know S&W used.
Help me out here-
WHY did I build the checkered ejector knob designed for PULLING and then put the thumb latch on the gun. I forgot.....
What is all the room behind the hammer for? Spare parts, or a place to carry a lunch?
We do know that the first prototype Hand Ejectors were built on modified Colt Mod 1892 frames! OK, so they already had DA Hand Ejectors in the works. Why build a SA?
The gun is an odd conglomeration of cosmetic touches from both Colt and S&W. English was not its native tongue.
