Gentlemen:
Thanks much for the info. I just acquired a Gaucher S/S 9.3x74R in Romorantin, France .... had no idea of its origins until finding this discussion.
It is different from the doubles shown in the Bretton-Gaucher site, in that the receiver resembles the higher grade box-lock, though the trigger guard is a plain design, and the buttstock is straight/English. There is no "Bretton" stamping, only "Gaucher" .... and that on the rib only. If any of you can offer any information on this line on doubles, I would be very grateful.
Alex
