1950s Vintage Levis Chambray Bomber Style Jacket M

1950s chambray bomber style jacket with dark blue knit trim. This looks exactly like one made by Levi's but there is no label in this. There is selvedge on the inside and possibly the Levi label has come off. The jacket has a few rust stains. The largest is on the left sleeve.

The zipper has been replaced with a modern metal zipper. This measures like a size medium. 22.5 pit to pit. 16-18 across the waist laying flat.
