Help with an older buckle back

[t4halo]

I finished putting my 73 Harley Ironhead together last month and thought I’d pick up a vintage cafe racer to wear while riding the old bike. A recent late night epay purchase landed me an older brown cafe racer. I know the Zipp zippers are probably German but can’t figure out these buckles. Anyone run across these before?

Thanks

Here are the Zipps. I’m thinking 60’s?

Here are a couple pics of the jacket. Weighs in at nearly 6lbs. Very nice stitching and I like the footballs on the elbows. It has a few vertical lines in the leather on the back. Fits me well. The pictures add a shine to jacket it really doesnt have.

Very cool!

I found what i believe to be the patent date on the Gutos (German) buckle. I think it has a patent date of 1953. With no label and nothing that looks like there was ever a label attached, It was probably a one off jacket.
