VTG 70s Horizon Mr Goodwrench Mechanic Windbreaker Jacket Navy Blue Sz S Or M

VTG 70s Horizon Mr Goodwrench Mechanic Windbreaker Jacket Navy Blue Sz S Or M Missing Tag, but I'm guessing S or M based on fit, measurement... Pit to Pit: 21 Shoulder to Hem: 25 Two side slit pockets, zip front, drawstring waist, mesh lining. When I got it there was something else between mesh and shell, but it had turned to powder/sand like substance. I shook it out and washed it, I'm assuming it was a lining of some sort that had dry rotted over the years. Jacket is in great vintage shape, patch perfect and intact.
