I picked up three caps on ebay, and only one of them fit me. So, here are the other two, for y'all to buy and enjoy. $8 for one or $10 for both, shipped. Paypal seems to me to be the best payment option. Unnamed, looks to be older, due to the union tag, but I really have no clue. It is size small. I don't have a tape, but the guy I bought it from said it was 21". Sale Pending Beacon Hill, medium, I was told it was 22" and that seems about right.
