When we got this jacket in we couldn't figure out what it was, but after a couple of hours of searching we concluded that it started life as mechanics coveralls, expertly converted to a mechanic's coat. More specifically, it is most likely the "Suit, One-Piece, HBT, OD7, Special" incorporating design improvements plus flaps to protect from gas infiltration (hence the "special" designation). The specification was PQD No. 92F, dated 23 May 1944. The color was the newer OD #7, the dark shade of late war items. This HBT worksuit was one of the most versatile clothing items of WWII, widely used in a variety of roles throught the American armed forces. The suit was used by mechanics, linemen and infantry personnel alike.
When we get articles like this one in, we try to keep as much as possible in its original state: we don't dry clean them and we don't patch minor tears. This one was no different. Each stain, each tear tells a story, and we chose to let the next owner decide whether and how to restore it. It is a 75 year old clothing article, with amazing feel and look.
We let the jacket sit outside and aerate, and we sprinkled some baking soda to eliminate musty smell. We attached our chain-stitched Bonehead patch using miniature rivets, as well as a discrete leather patch on the back seam.
There is no size marking, but we are certain it is a 40. Shoulder to shoulder is 19 inches and pit to pit is 24 inches. It will be a roomy Medium and a comfortable Large.
The enclosed photos have been minimally processed, so the colors are true (as are the stains and tears). Please study them carefully before pushing the Buy button, as we do not accept returns on vintage items such as this.
