Vintage Deutz Allis R7 Gleaner Combine Belt Buckle RJ?

Description

Selling this vintage Allis Chalmers
R7 Gleaner Combine
7020 belt buckle.  Looks to be in very good condition.  There is some places around the inside edge but I don't know enough to say if this is a defect or just the way they were made.  You can see what I'm talking about if you enlarge the image of the closeup front.
It looks like there might be an "RJ" stamp on the back.
I've marked as new because I d
on't think it was ever mounted on a belt.  It was in a box with some other belt buckles from my wife's grandmother's collection.
Size 3 1/8" x 2 3/16"
