Again from ebay, a pair of Turbo/R tires that actually look pretty decent for their age (I still wouldn't trust 'em to ride on, however):





Full slick tread. I'm thinking for sure the Turbo/Cs must be the combo center rib/herringbone but as yet haven't been able to confirm. Having fun looking, though

[MENTION=505332]alexihnen[/MENTION] these are currently available for less than $40 for the pair, with free shipping. For a wall hanger, you can't beat that with a stick. Auction here: Specialized Turbo/R

Note these are 27 x 1 1/8" and not 700c; I didn't see a size called out in your OP, so...maybe they'll work for you, maybe they won't.
