This vintage jacket was made in the 1930s from Penn-Rich plaid mackinaw wool, and bears a “Workman’s” tag. The coat is a classic work mackinaw cut, double breasted with handwarmer pockets and flaped cargo pockets.  This one has a button on throat latch under the collar, and is fully lined in a second layer of plaid mackinaw wool.
