Nothing that rare, but a decent visor cap that I found on Ebay for a very good price.
Typical wool twill blend found in contract caps, this one made by Franz Ritter, although most of the logo has flaked away over the years.
The eagle is mounted rather high, but it appears to have been there for some time.
Some moth nips, but overall, a solid cap with a good interior. A couple areas of less than skillful sewing, but I suppose not unique.
