Have a question about the French proofmark on my Francisque Darne 16 gauge. The crown over R marks it as an ordinary reproof with 70mm chambers (2-3/4"). Barrels are 17.0 mm (16 gauge). The five stamps are not proofhouse, but an indication of grade from the gunmaker. Believe they are backward "F's" with capital "D" uniting them.

But, I do not know that the rhombus on the right is that has the letters S over a small capital R. Grateful for assistance.

Regards, Tim
