Is that the Classic Arms New Orleans Ace Pistol [Kit]?
It sure looks like it along with the similar barrel measurement.
Some of their models are also sold already factory finished.
That certainly looks to be the same. The piece I have has no marks or stamps of any kind, but the parts look identical. Thanks articap for all your help. So waddya think? Live load or not?
Powder measure: Free at most public ranges. Pick up an empty 9mm pistol cartridge and use it to measure the powder charge. It will hold approximately 13-14 grains of black powder, nearly perfect for the derringer.
