Jerry thinks there is a "K" on the forend lug. My 1st thought was György Kirner due my thinking he worked at FEG and with Frommer but this is from memory and may have been a dream. I have to make more and better notes. But Rudolf von Frommer married Leoine Kornfeld(1874 - 1950) and I guess that to have been in the 1890s. So if one of Leoine Kornfeld Frommer's nephews decided to follow Rudolf von Frommer in the gun trade, it could account for the "K". I don't have a specific name but will continue to search. But Rudolf von Frommer was long gone by the date of proof of Jerry's example.

Kind Regards,
