I handled a Brancquaert similar to this last year at the Southern SxS. Fellow had a number of pigeon guns for sale both hammer and hammerless. That gun did not have the engraving coverage as the one Bob Ney has for sale and the price tag was just north of $13k. I’ve been told Mr Brancquaert was a competitive pigeon shooter who had his guns made by several Belgium makers. He had them made for his own use and also sold a few to his friends and fellow pigeon shooters.
