Canada WW1 CEF 77th (Ottawa) Infantry Battalion Shoulder Title Number.
A single piece, darkened copper shoulder number to the Canadian WW1 CEF 77th (Ottawa) Infantry Battalion.
Light wear to front, with title just slightly bent/out of shape.
To back are two copper looped lugs, firm and original.
Maker marked to back to "Caron Bros 1915" - I think... the lust number is hard to read.
