No, the chape is wrong, needs an external metal piece. The mouthpiece is wrong. More like something much older.
Anyone with pre-1916 rifle marked to the 16th Battalion might want to post or PM me the serial number as I have a list of about 100 rifle SNs with the names of the men they were issued to in 1914/5. Sometime in 1915 the order must have come down not to bother recording that information as it simply stops. The logical conclusion is that casualties were so heavy and as a result there were so many rifles changing hands it was impossible to keep up with it.
The scabbards shown are British modified fitted with a P1888 mouthpiece to take British frogs. Mine came with a Brit P1914 frog.
Century Arms in Montreal got the HMS Canada guns and sold them in Canada
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.

There is the right side of the butt and the odd metal bit.
