Great bayonet. Adding to the discussion of cut down bayonets, there were Pattern 1907 bayonets cut down by Turkey in the 1940s, often with reworked cross-guards to adapt them to a Mauser rifle. These are usually thought to be from a batch sold post-WWI in the 1920s, as well as possibly a number of bayonets captured during the fighting at Gallipoli. Those are usually seen in steel scabbards.
The hole in the pommel was approved in the list of changes for 1916 I believe, but often seen added on reworked bayonets. It can be a helpful identifier, since it should not be present on a 1915 or earlier Pattern 1907 bayonet as originally manufactured.
