Hi everyone thanks so much for your input! When I did some google searches, I didn't use any English words so I pulled up a number of sellers, mainly in Germany it seemed. The handful I found which showed the exact same coat said mid century although one interestingly said a police coat in the 60s. Now I never believe just one old selling listing, but there were a few which I found interesting. BTW I used google translate to copy and paste text to translate it.
It looks in really good condition because prior to taking the photos, I spent a lot of time with leather conditioner on it! You should have seen the state originally! I don't know enough about leather to say how thick it is, but it's bloody heavy!
As I have it in front of me, I have the benefit of looking closer and I just don't feel 80s fits. That doesn't mean I am thinking 40s. I think it is some kind of utility/uniform as there seems to be quite a few around, all identical other than different colours. I'm afraid it still feels as a mystery to me so I'm going to do some further research. Thanks again for all your time and help with this.
