Interesting markings. A hard one to find and being a conversion even makes it better.
Great markings and front side condition
Lovely buckle Zep, always love conversions and the markings are great
Very nice Yuri. I would love to have that buckle.
Both back and front are superb.
Please notice the KH instead of M4 here if someones missed that.
Not a conversion, but an early Franke buckle in nickel with the same catch. This example shows similar maker marks in the M4 format.
