KanawhaRanger said:That may be the same John Armstrong of Emmitsburg, Md. That's not far from Gettysburg. In fact it is believed that he was born in Adams Co. Still wouldn't explain the Philly address and this rifle is of a different type. He apprenticed under George Schroyer and his rifles show that influence. I don't have enough reference sources with me to see if there was another Armstrong in that city. Kauffman's book doesn't show any other Armstrong.

This is likely an Armstrong hardware dealer/importer.
John Armstrong the Maryland gunmaker did not make this lock. Its a typical Birmingham import lock brought into the US by the thousands and marked with the importer/sellers name either when made or after arrival here. A lot of them were surely shipped direct to Philly from England.
Many/most American guns had import locks. England had the ability to make large numbers of locks at low cost.
Armstrong made locks but they looked nothing like this and he engraved his name of them being a skilled engraver and they were only used on his rifles.
