Maybe this is common, but the first I have seen. (Pictures as soon as possible!)
Just forward of the front ring on the barrel is a small mark of 'byf' in a shield. To the right of the shield on the barrel is the date(?) '44'
On the front ring the is only the 'Eagle 135' Waffenamt. No other markings on the top of the front ring. Machining marks(rough) are consistent across the top of the ring and it does not appear to be altered.
Bolt (round gas ports) s/n matches the receiver.
Bottom metal is stamped/welded w/ lock screws and without s/n. 'byf' on floorplate. 'byf' and two 'eagle 135' Waffenamts on front tang.
