Rugged K Union Made Vintage Men’s Weathered Lined Denim Jacket M/L USA 70s retro

This is a very worn and weathered jacket. No size tag so please check measurements. This jacked it dirty and worn which is what makes it so cool! Union made, unique snap closure with “k” on each button. I believe the lining is wool but not positive as there is no materials tag. I can’t find much about this brand which is what makes it so unique!
