Hello stripped the rear hub satisfied my curiosity as to what is in there and have rebuilt both wheels.
I have been in touch with the national cycle museum in Wales and having supplied photos and further info they have informed me that the bike is a Silver Sunbeam Light Roadster dating from 1934/35. The adaption of the front brake obviously they cannot explain. If allowed on this forum my further thanks to Scotford Lawrence from the national cycle museum for the info. Cheers.
