Looks fine I would try and get it for 85 that would seem like a fair price to me
I do not think this is a "droop tail" buckle. the back of the eagle is to straight, if i'm wording that right, if you look up " luftwaffe droop tail belt buckle" on google images i think you will see what i mean.
Droop tail are only in aluminum. In this condition $100 is to much. I have one without the tab that I would sell for $50. It is also a Schmol and comp.
Here is a flock of droop tail eagles.
For me $100 for the buckle in that condition is too much
