80s or early 90s vintage Goodyear F1 Racing Members Only Jacket (Medium)

Not sure of the exact vintage, but this is an 80s or early 90s members only style Goodyear Formula 1 racing jacket. The tag states only Goodyear, and does not list a size. It's probably a medium, since I wear a large and it's a bit on the smaller side. It has a blemish shown in the photos on the right front just above the buttoned pocket. Zipper is marked with YKK for Yoshida Kogyo Kabushikikaisha, or Yoshida Company Limited.
