Dr. thanks and I will post a picture showing Glahn's engraving with his signature for people to use as a comparison. As far as some type of symbol used instead of a signature, I don't know of any for Spangler. I do know that some engravers used a symbol and maybe all did, but again I do not know.
Richard, that is a very life like setter, but I would be guessing on who did it.
In records kept by L.C. Smith Maker and the Hunter Arms Co. it showed who transfered from Syracuse to Fulton in 1889-1900 when L.C. Smith sold the gun works to John Hunter.
The Spangler brothers and Jacob Glahn and his three sons, George, Theodore and Gus. Jacob Glahn died in 1892 and the sons continued to engrave at Hunter Arms until around 1905.
In "Steel Canvas" R.L.Wilson describes Theodore as a very talented engraver who engraved a Colt gun for Teddy Roosevelt, and Jacobs brother Wilbur went on to become one of the Colt Firears Co's greatest engraver.
So until more signed engraved guns are found for comparison to ones that aren't signed, hopefully we can find a symbol to identify different engravers. I'm sure they all have them, and most of the engravers back then knew each others work without seeing a signature.
DrBobs signed Lefever.
This is signed Glahn sc (sc means scribed)

this one is not signed but these two guns are consecutively numbered and would most likely be the same engraver.
