This vintage plaid mackinaw coat was made by the Soo Woolen Mills of Sault Ste. Marie, Michigan immediately after WWII. It has a surcoat zipper attachment and length. The main zipper is a rare transitional talon- with a Talon marked stop box of the type used in the mid-late 1940s. The main zip has a square sided, square holed puller, a type used very briefly as they were transitioning between the square edged pullers with a small hole and round ended pullers with a larger hole. The pockets zip with bell shaped, round holed Conmar zippers. The overall cut of the coat is interesting, with its long rear pleat topped with triangle reinforcing stitching and a belted, buttoned back. Most plaid mackinaws were of very traditional designs which changed very little over the years. This particular Soo model was very modern and sport for the time it was made. It is lined in red flannel, and is marked young adult age/size 20, which going by the measurements, is about a men’s size 44 short.
