It is known that Folsom worked in Memphis at some time and it is possible and reasonable that he made deringers there and in St. Louis but with a different marking, leaving off the St. Louis in the case of the Memphis guns.
A. WEISGERBER
#256 Weisgerber was an authenticated maker according to newspapers of those days of derringers, shotguns, and rifles. To date, I know of one rifle and two derringer pistols, one of which is in my collection. Notice the heavy bag grip and the unusual shaped hammer. The forearm nose is fluted. All parts are German silver, not engraved, and the inlays are held in place with wood screws which is contrary to the vast majority of the others in my collection. Its caliber is .440.
The only markings are on the top barrel flat as follows in two lines:
A. Weisgerber & Co.
Memphis, Tenn.
J. F. MERRIMAN
#219 Again we have a Memphis maker, whose name was Merriman, that little is known of but he is authenticated as a derringer maker by newspaper accounts. This gun has a rounded face European style hammer that appears to be original with the gun and all furniture is German silver. There is some engraving on the inlays. There is no provision for a ramrod. Its caliber is .410.
