I've had an A. Jansen 2 3/4" 28 ga. boxlock for quite a while. The gun looks exactly like a Francotte 14E but with the Jansen markings (and Brussels Belgium location)engraved on the barrels. The gun has identical case coloring and basic engraving to other Francottes I own. Back years ago, someone told me that Jansen was a smaller Belgian gunmaker who generally only made bespoke guns and bought barrels and frames from Francotte. For quite some time I've wanted to learn more about Jansen and as a newer member to the site decided to see if anyone can shed further light on them for me. By the way, the gun has 26" F/F tubes, ejectors and third fastener, 13 15/16" LOP over a checkered butt and weighs 4# 8oz. I don't know who to submit pictures yet but will try.
