Carfin, buckle is original and the maker could be J C Maedicke, not in very good condition though, looks ground dug then shot blasted
Thank you very much Ben.
I purchased this buckle & the leather last week for 10 euros, the used condition looks me like a fake.
Best regards from Alsace : France.
Carfin for 10 Euros you have a a good deal my friend lol
