Very interesting article Fingers. Thanks for posting.
While it may be true that no Glassick &Schneider guns were purchased by the Confederacy, it seems likely that the few revolvers they did make were probably purchased and used by individual soldiers in the Confederate Army.
Anyway, there were clearly very few Griswold & Schneider marked Colt revolver knock-offs produced. A month or so ago I tried to correlate the number of Griswold & Gunnison revolvers that were produced during the war with the number that survive today, and came up with 1 gun still existing for about every 14 guns that they produced. Assuming that about the same 14 to 1 relationship should hold for Glassick & Schneider guns too, I figured that about 42 Colt knock-offs were produced by G&S based on the fact that 3 are known to survive today; however, the the higest serial number that has shown up on a G&S revolver so far is 27, I think. So it seems clear that at least 27 were made but maybe as many as 42 or so.
There was another article concerning Colt-type revolvers in the Memphis Daily Appeal newspaper that appeared in that paper about a month or so before the Dec. 1861 article that first mentioned the Glassick & Schneider revolver. The earlier article mentioned that equipment for making Colt type revolvers was then at the Navy Yard (in Memphis). I don't know if that machinery was used to make the Glassick & Schneider revolvers or not, but I imagine it was.
The fact that Glassick & Schneider ceased manufacturing their brass-framed Colt knock-off revolvers in Memphis just a few months before Griswold & Gunnison began manufacturing what was an ialmost dentical revolver in Georgia a few months later, seems to me to have been more than just a coincdence, and may have involved using the same machinery to produce what was essentially the same gun - except for a half round barrel being used on the G&G gun and an octagonal barrel being used on the earlier G&G's.
It would be interesting to know if the G&G brass framed guns were made on the same equipment as the earlier brass framed G&S guns.
