Kim,
Thanks very much for the link!
I have been going over this revolver for much of the afternoon. These are my thoughts:
Schneider & Glassick went into business as Memphis Novelty Works. Their wares were marked as such, or just Novelty Works immediately prior to them fleeing Memphis. They produced swords and many other items.
This revolver, supposedly #3, is marked "Schneider & Glassick Memphis Tennessee" on top of the barrel. As SN #3 it would most likely not be marked this way. Red flag #1.
The 3-4 extant S&G revolvers, even the iron framed 12M, have brass backstraps and brass trigger guards. #3 has an iron/steel backstrap and trigger guard. In the 1920's-1930's, when original ACW period revolvers were selling for cents on the dollar, there were quite a few home gunsmiths who created guns using parts from old guns to create spurious shooters. The only Colt Navy that had the steel gripframe was the 1861 Navy, and that could have been the source of those items. Red flag #2.
I have Googled "The American War: Weapons Of The North And South" and get absolutely no hits. The Guns International site does not give any information about the book. What I find curious about its veracity is photo #2. The partial picture above the S&G #3 is a George Todd revolver offered as a photo in the book by Gary Hendershott and the author takes it as an authentic George Todd revolver. George Todd manufactured very few revolvers in Texas, his history is very sparse, and that was immediately prior to the ACW. That said, I have a photo of another George Todd revolver that was offered for sale by Hendershott a few years ago.
Note the difference of the wood condition at the backstrap/ trigger guard juncture.


I find it difficult to believe that one individual could come into possession of two rare George Todd revolvers, thus I doubt the veracity of the book. Red flag #3.
The seller shows no photos of the serial number, nor any other photos to prove that it is as promoted.
I just received an email from the seller. He wants $165K for it,

and his only provenance is that it was "found in a little junk store over 40 years ago". Red flag #4.
Any comments appreciated.
Regards,
Jim
