1952 BSA B33 which is a 500cc over head valve single. This one has a current V5C present and information on file showing the engine and frame left the factory together, so it is not a piece up but an authentic machine.
older resto as the tin ware and wheel rims look powder coated, which is good hard wearing stuff. The bike looks to have had a brand new carb. It starts easily and runs superb. it is charging strongly as well. So this is oily rag but excellent mechanically. one to use everyday.
