I wonder if you can help, I have just purchased a Sunbeam Rapier Series 111A and it has an engine with cast iron head and twin Zenith Carbs, with an oil bath filter with only one spout. it carries an identification on head of C22155. and on block of 3802520.
any ideas if is is 1725cc or 1495cc and where it came from ?
any help gratefully received
thanks
Royston
