Fantastic Kerner - Anson Body Action with Emil or Ernst Kerner's initals on the tubes along w/ the initials >>F.A.<< on the flats.

Now there was a Fritz Albrecht but I am not sure he was active in the mid to late 1920s. But Gebrüder Adamy was as it was founded by Albert & Franz Adamy in 1921. So I would say Franz Adamy had some part in the tubeset knitting. You see the initials on many Suhl doubles from this period especially those of Charles Daly, being the last of his quality offerings.

Times were most difficult in this tumultuous period & many concerns faltered. In 1919, Ernst Kerner partnered with Carl Funk and by 1923 Ernst Kerner had hung out his own shingle while Kerner & Sohn(Emil) really began to falter and by 1929 looks like it went into receivership and was dispersed where in 1930 Emil Paul Jopp of Albrechts landed up with it. Ernst was in full control & is noted as being the designer of a boxlock platform - Erfinder selbstspannender Jagdwaffen. Too Ernst Kerner was supported by a machinist by the name of Johannes Viereck, who might have performed the heavy lifting on the platform?

Have you a better image of the side of the frame?

Cheers,

Raimey
