Bob:
The lack of the Francotte name, in any form, on the sideplates of this gun doesn't bother me @ all.
The lack of a 'crown over AF' on the barrels, however, does send up a big red flag, @ least based on what little I've learned over the years. Granted, I haven't seen many 1970s vintage Francotte guns.
Thus, I'm trying to learn something here relative to guns from that era.
With that in mind, and based solely on the info and pics we've been given in this thread, where do you feel this gun falls in the 4 options labeled A.-D. I posted above?
Thanks.

Always looking for small bore Francotte SxS shotguns.
