A fellow KFer who doesn't frequent this forum called today to chat and in the course of conversation told me that he has a Darrin folding top frame, a set of landau irons, and a set of hold down nuts that he would like to sell. He said the top material is incorrect and needs replaced. He is asking $2500 for the frame, or $3000 for everything. Sorry, but I do not have any pictures so I don't know condition.
PM me if you're interested and I will pass along contact information.
These things no longer grow on tress so if you need one, here's your chance!
