I'm trying to track down the maker of a 1929 production Prussian Daly. (As many Daly enthusiasts are aware, the post-WWI/post-Lindner Prussian Daly story is a complicated one. The serial number ranges are all over the place and several makers have been associated with these guns including Heym and August Schuler.)

The gun in question is a fairly minty model 135 12 gauge gun. The ONLY unexpected marking is on the barrel flats - the initials "F.A." Everything else from a proof mark and barrel marking perspective is what you would be expected for a gun of this vintage - nothing to indicate a maker. Note that these initials are NOT ahead on the barrel flats where (what are thought to be) the barrelman's initials are often found on a Lindner-vintage Daly.

Anyone want to take a stab?

Thanks,
Ken
