Vintage 60s 70s Leather Jacket East West Musical Instruments

This jacket belonged to a seamstress who worked at East West Musical Instruments. I believe it was some sort of practice jacket or made out of leftover materials, so it does not have the official tag/stamp in it. One arm was smaller than the other and a gusset was added in the armpit to make it larger - see photos. This is undetectable when worn but also adds to the character and patina that this jacket already has. It is now the perfect 70s leather jacket. Has brass snap closures and a wild collar (it is symmetrical, just was lying weird in these photos). Unlined.
