The gun was made in Germany for sale by Francotte. It was proofed in May 1924, under ledger number 235. Since there is a ledger number, it was likely proofed in Zella Mehlis and was therefore likely made there or near there. I do not believe it was made by Bernhardt Merkel because the Merkels operated in Suhl and would have used that proof house. The gun was rechambered to 12 ga 2 3/4" and re-proofed during June 1938. All the proof marks are German, but there is a mark on each barrel flat, that is not a proof mark. It is a circle with either RB or AB under a crown. This could be a maker's mark or a workman's touch mark, but I do not recognize it. Maybe Jani or Raimey will recognize it.
