OWD, I want to see the weight of the barrels on the flat of the water table, it is allways indicated with Belgian made guns.
OWD, Defourney made some self opening double guns based on the Beesley action, there is now one for sale in the next Gavin gardiner auction Lot 244. Here is the link:http://www.gavingardiner.com/BidCat/detail.asp?SaleRef=0009&LotRef=244
Because it is a 2 barrels set, cant you tell is the barrels have the same S.N. and are they prooved the same time. Pete is right about the proof controller and date (1950)
