The BBF barrels are 23-5/8", or 60 CM. The shotgun barrels are exactly 28". My experience is that export guns had even inch barrel lengths. The Quality 1 stamp on the rear lug of the shotguns barrels was usually applied to export guns. This one has it. That was East Germany trying to earn hard western currency. I doubt that East Germany sold the gun directly to West Germany. I know they sold lots of guns to the Swedes. But this one wound up in Ulm, West Germany somehow for the BBF barrels to be installed.
