Well preserved standard Nicasil cylinders of a R65, 50hp with pistons, mileage 46940, they are not shortened or otherwise processed.

They were mounted on a racing R45 and are marked 475 cc (…. a rogue, who thinks evil of it…), the original marking was removed and the new one hammered in.

The project was probably never fully completed and is unlikely to have been raced. Good and clean condition
