Geno have it the right way,Francotte make them. Here is one on a German site:http://www.jagdwaffen-strank.de/en/enindex2.rxml
http://www.jagdwaffen-strank.de/en/enindex2.rxmlI think I recall Forgeron being sourced by the Weipert craftsmen for components and I'm sure many other Belgian craftsmen.
Is it this one?
Not a Czech gun but these early BuHags(a conglomerate, or sub to a conglomerate, similar to Lovena) are the deal of the show and I know I've informed some and may be lashing a dead horse. I shoot one all the time and the early ones say up and into the 1960s are composed of pre-WWII(during) components and potentially made by pre-WWII craftsmen or their apprentices:
With the "Pipe" style side frame reinforcement, the frame may have been sourced from Merkel components and the overhanging scears are pretty robust.
Kind Regards,
