DA280 rifle and bayonet are in my possession, year of production 1915, serial number 48 GO, M68 stamped on the top of wrist of stock, as well as 280 stamped into the wood on the right side of the butt. Bolt is also marked as DA 280. The Bayonet itself is marked DA 280 as well as M65 on the grips.

And the odd thing is a round bit of metal is stuck on the right side of the butt stock in between the Ross Rifle Co stamp and the III marking.
