Not sure which bayonet its for, but its definately from the 1800's.
The oliver pattern frog is the only CDN made leather frog made in the 1900's. I can say for sure that its not a Ross frog, or for a 1903/1907 bayonet, and definately not from WWI or later.
I would hazard a guess that its for the 1860 sword bayonet - it looks too big for the 1888 bayonet, but thats possible.
