bp, I enjoyed reading your interesting article. I realize you are mainly interested in the replicas of the Schneider & Glassick revolver, but I want to run something by you. If you think has merit I hope you will comment on it, or if you don't want to comment on it yourself, I hope you will at least forward it on to the people you know who would know something about the originals.
Schneider & Glassick (of Memphis, Tn.) and Griswold & Gunnison (of Georgia) both produced brass-framed revolvers manufactured on the Colt 1851 Navy pattern.; in fact, except for the different names and different shaped barrels they look remarkably alike to me in the pictures I've seen.
No one knows exactly when Schneider and Glassick began or ended production of it's Colt type revolvers, except that ithey had commenced production no later than Dec. 8, 1862 when an article praising their product appeared in a Memphis newspaper.
Memphis fell to Union forces on June 6, 1862 and no S&G's are known to have been produced after that date.
New Orleans fell to the Union a little earlier than Memphis, surrendering on April 28, 1862.
One of the principals of what later became Griswold & Gunnison was from New Orleans, and supposedly went to Georgia when that city fell, and started manufacturing G&G revolvers for the Confederacy, beginning in July of 1862.
I wonder if anybody has ever checked the Schneider & Glassick brass frames to see if they could determine whether or not Schneider & Glassick revolvers were made on the same equipment that produced frames for the later Griswold & Gunnison revolvers?
I'm thinking that G&G may have bought the S&G equipment sometime between the date New Orleans fell on April 28, 1862 and the date Memphis fell on June 6, 1862 and moved it to Georgia, and that these two brands of revolvers were essentially the same except for the different barrels.
I've read that 3,600 G&G revolvers were produced from July 1862 to Nov. 27, 1864 and that less than 250 still exist. No one knows how many S&G revolvers were produced but production is believed to have been small, and probably lasted no longer than a few months. Using the same produced to surviving ratio for S&G as for G&G, which is about 14 to 1, there were probably no more than about 42 S&G revolvers produced.
