There are several prints/smoke pulls of patterns/engravings done by L.D.Nimschke for A.G.Genez on his fireams. (L.D. Nimschke, Firearms Engraver (Wilson)
All SxS's as I recall but one is a derringer lock-plate marked 'A.G.Genez' signed with a simple 'N' where the hammer would cover it when in place.
Prints are dated in the 1869,1870 era.
The SxS pulls are everything from the simple name/NY marking w/double line border on lock plate, another Name w/Pat. applied for/April 20th, 1867,,to extensive scroll coverage on lockplates and actions.
A presentation plaque pull and a looks like a rib inscription pull (Made for...) as well.
Must have been a pretty good customer.
