This jacket was made by Ralph Lauren under the Polo label. It was part of their Sun Valley collection. The jacket is based on 1930s wool work jackets, with a fold-out vest/chest protector, buttoned throat latch, half-belt back, low slung buttoned side adjusters, buckled cuff belts, and a zipped breast pocket. The main zipper is a bell-shaped Talon repro.
Chest (pit to pit): 24″ (doubled = 48″)
Shoulder to shoulder: 20-1/2″
Sleeve (shoulder to cuff): 26″
As always Spencer, nice photos and information , you know your clothing for sure….Love the looks of a lot of the Ralph Lauren vintage lines , like this jacket ,very nice! but he like many others took the manufacturing to China. I’d gladly pay more for the clothes if they were tagged made in the USA.
