I have a brand new, out of the box, never worn Amzi Williamson cap.
It is a 7-1/8.
Above is a link with pictures and comments from pleased customers.
These are usually 105, but I'm selling this one for $100, that includes USPS priority shipping, cont. 48.
Money order or paypal (add 3%)
I'm also willing to trade for a quality (NJS********** or Sam Dolin) CS gardner canteen, new or lightly used.
