German Silver Belt Buckle- Barrel Racer

A couple of tarnished areas or where finish is rubbed black. I tried to buff it. I think this one is from the ‘50’s, ‘60’s, or ‘70’s - it has been in our Family's western attire collection for a LONG time! Likely bought new by my Step-Dad. Silver & Brass. 4 inches across. Almost 2 3/4” tall. Thought to be an Irvine & Jachens Inc. brand; although, the back doesn't say. I am still investigating this...
