Vintage Leather Jacket

Super sick vintage leather biker jacket in great condition, comes with a pin on the collar. Guy I bought it from was claiming 70s but I’m not too sure, I think it’s somewhere between the 70s-90s. Has two little holes and a red stain on the collar from where a pin used to be, perfect place to throw another pin on and cover that up. Has a plate on the lower back. Size M/40, see photos for measurements.
