DM received an order of Adventurer hats with a snap brim, so he's selling them for $98 plus shipping. I don't know the exact dimensions of a Fed IV, but these look pretty close to me... especially since both are advertised as "Indiana Jones" hats. If you've been wanting a Fed IV and couldn't justify the price, I think now's your chance to get a name brand knock-off. Get 'em while they're hot!
