Ken,

I can't come up with any obvious maker with "F.A." the only two that come close for the time period are Franz Rudolph Albrecht and one of the Anchutz brothers Fritz. There was two or three gunmakers named fritz Anchutz.

Keep in mind that the initials may be the person running the company and not the company name. Dalys made by F.W. Heym Company are marked "A.H." for August Heym who was in charge of the company when they were made.
