Here is a photo from the Shelby Showcase at the Toronto auto show. In it you can clearly see the "flip-top" roadster (CSX2196) and the 289 FIA roadster owned by Lynn Park (CSX2259).
But can anyone identify the 289 USRRC roadster (#52) with the racing windscreen? Is it CSX2431 or CSX2494 or one of the other ones? Thanks for the help.
