Robert Brodin in Sweden, very kindly sent me these pictures of his Stephen Roche Course Villach. The specification includes a mixed Campagnolo groupset and handbuilt wheels with Campy hubs. Frame features the attractive chromed straight forks.
I recently got in touch with a seller of a NOS Villach which features white painted and curved steel forks. The Stephen Roche website of the time confirms that a curved fork was available as an option, so its reasonable to conclude that this is original-and rare. The seller bought the frame from the Carrera factory. Note the Carrera marked rear drop outs
