This vintage jacket was made in the 1930s by the Pendleton Woolen Mills of Portland Oregon. It bears the early style Pendleton label, used up to the early 1940s. The jacket is a mackinaw wool work style, with a distinctive combination yoke and shoulder reinforcement, rounded collar points, D-shaped handwarmer pockets, buttoned side adjuster tabs and button adjusters on the cuffs. The zipper on the jacket is a 1950s-1960s replacement, made by Talon. As is typical of these early mackinaw work jackets, this one is unlined. With a 49″ chest, this would best fit a size 44 or 46

Chest (pit to pit): 24-1/2″ (doubled = 49″)
Shoulder to shoulder: 20″
Sleeve (shoulder to cuff): 26-1/2″
