Hello. What a great group! I have a question concerning the Fed IV. I recently bought a Federation IV Deluxe in moonstone from Hats Direct and the felt is thick. It's a heavy hat, and I really like it. A couple of weeks ago I bought a brown Fed IV Deluxe on ebay and the felt is much thinner. The difference between the two is significant. Is it common for two Deluxe Feds to be so different? Thanks.
