Sunbeam S7 deluxe 1950 & watsonian Monoco sidecar

I have owned the sunbeam since 1996.Its condition is tidy but used.it has a Stewart's finned rocker cover, sump spacer, spark enhancer,twin spark coil.original features are rubberised leather seat,handle/bar leaver and switches.Also with it are original mudguard which will require attention, carb, pillion seat etc.I put in an exchange crankshaft and new bearings 80 miles ago.She starts and runs very well,but unfortunately has developed an oil leak at the rear of cylinder.The sidecar is a watsonian monoco with a good working brake. She handles very well.
