BSA Gold Star Scrambler project 1955 CB32 barn find

BSA Gold Star project. don't have the engine! Unfortunately what you see is what you get. Looked on the BSA gold star page of the bsa owners club and I think I'm correct in saying this is a 1955 frame.
The rear wheel and the one without a tyre are gold star. The front is from a Jawa ? The magneto turns ok but I couldn't get the end cap undone to clean the points so I cant say it sparks.
The gearbox turns smoothly the oil tank has no holes and has original paint and transfer. The fuel tank has a big dent in the top and into the front left side repairable I'm sure. sprayed a coat of primer to stop the frame rusting. it also shows the additional welding to the frame. I'd prefer cash on collection or delivery by arrangement. Any questions please message me.
