The only markings are on the top barrel flat as follows:
E. R. Sieber,
Nashville, Tenn.
H. G. NEWCOMB
H. G. Newcomb is a little known maker of Vicksburg, Mississippi who made his own derringers. I have only heard of two guns by this maker and they are in a collection in Mississippi and maybe sometime we can obtain this specimen for photographing and describing.
Apparently Newcomb was active about the same time as O’Dell but he lived into the early 1870’s. Two of his derringers are known and one is even more ornate than O’Dell produced guns while the other is very plain. It is rumored that some genuine Henry Deringers were agent marked with Newcomb’s name but I have never personally seen one of these guns.
UNKNOWN
#221 Here is an unmarked derringer that could have been made either in Nashville or in Memphis according to the sheath trigger and the flat butt. Bitterlick produced guns of this style and marked them but I do not have one for my collection. Notice that this is made of curly maple rather than like all the rest of walnut. The full octagon barrel has one silver band at the breech. The tang is marked with “#1”. There is no way to determine whether this gun was made in Nashville or Memphis. Its caliber is .480.
