Help dating a leather jacket - Zipp zipper

[Natalie Liddle]

I’m looking for some help identifying the age of this leather jacket with a Zipp zipper. I’ve not been able to find an example of this type of zipper on any online photos. I was presuming the jacket was 70’s but I’m not so sure- definitely has an older feel with the lining and label. Any help appreciated

The zipper does not offer much clue on this jacket. It has all the look in style and material from the 1970s as you thought.
