The wreaths are not Real easy to find, but they are seen from time to time. You're probably looking at about 100-150 bucks to pick up a decent looking one like Bob showed you on his. It's a shame that the sweatband is so fragile and deteriorated on this cap, as otherwise the rest looks fairly decent. I like the owners initial button inside on the band(the "F"). If the owner is asking 800 in it's present state-which is a little high, I would offer him $600 and let him know of what more you would have to put into it to get it back into right shape. Someone like BenVK should be able to help you with that sweatband-you should contact him and see what he suggests.
