Vintage Burton men’s 40 wool brown overcoat hidden buttons velour collar Canada

Vintage Burton men’s 40 wool brown overcoat hidden buttons velour collar 46 Long, 3 outside pockets and 2 inside. Made in Canada. The top button hole on the folded collar doesn’t seem to have a corresponding button and I can’t see where one might have been. There is a tiny flaw (see pic) but really barely noticeable, and the lining has had some repair (also pic). Not sure of the age but it’s in great shape! Disclosure: there many be other tiny flaws but they are hard to see if so. This has the cleaner’s tag still on it. Note: the coat measures 44 but upon research, you need to subtract 4 inches from the measurement to get the correct size.
