An original US M1943 jacket. This is the MQ-1 variation, thought to date from 1946 and including internal buttons for a liner, before being officially adopted as the M1950 tunic. Grubby and worn condition, perfect for that in-the-field impression, has tag but it's unreadable. Measured by hand as follows;
Chest - 20.5 inches externally, so approximate 38" chest size, seen here on an approximate 38" mannequin.
Shoulder seam to cuff - 22 inches
Shoulder to shoulder - 19.5 inches
