Was it a seller on Ebay or do you have any details regarding who you bought it from? I'm sure that would help people, since there is bound to be someone here that has done business with the person if they are a good seller. I bought a vintage gen crown recently and the seller was over in Switzerland. I posted some info about it (on another board, actually) and low and behold, a member knew the guy and had done business with him in the past. He confirmed he indeed was a good parts supply guy and my part was gen.
What did you pay for it? I just picked up a Tropic T19 service dome from Clark for my 1680. Can't wait to get it installed. I looked at gen but they were way more than my budget allowed with the other things I am doing to it.
