Vintage Reversible Blue Plaid to Cranberry Coat L

Coat was found in a second hand shop but I have barely worn since purchase, is wool feel but no internal tag present. Small imperfections do exist from the coat's previous life: A few small white specs that look like they may have been paint on the blue side and one small hole near the right sleeve on the red side. Blue is a medium slate blue, Red is a cranberry. No size tag present but fit me best as a size 12/L Buttoned shut flat measurements are: Chest: 20.5" Bicep: 7.75" Length: 36"
