Found time over a few days to strip the sunbeam. Have included photos of stripped frame,the head tube with built in bearing cups,the top of the fork tube with cuts and the captive lock nut which screws onto the top of the forks. The ball bearings in the head tube were two different sizes with the top bearing having very small ball bearings and the bottom almost twice the size of the top. Also found another number on the rear dropout which is L W R H not to clear in my photograph Cheers.
