Featherbed frame top rail

I am having trouble with the lack of a frame number , but noticed that the top rail where the tank sits on , on the right hand side is pushed in on the inside of the frame to the rear section of the rail for about one foot . Why is this done .is it common on all frames, the push in is about one third of the diameter of the tube . Would the frame have been done like this to fit a norton single .

Yes you hit the nail on the head its a singles frame , stamp marks are on the rear left hand gusset , Singles had 4 or 13 on the top of the number this tells you one is a 500 ES2 and the 13 stamp mark for the Model 50 . 350cc but both very good frames, have fun yours anna J

Hello Anna

Thank you for a very helpful reply . It gives me something to work on when trying to register my Triton . I have an es2 engine that is virtually unused but the cases are from a model 50 . I might try and register the bike as an es2 or model 50 . The numbers in the log book say 390863 but I wonder if that should be 13-90863. I saw the cosmos norton on their site that you mentioned on another question I had , that is a really nice bike but out of my league . Thanks again and I will carry on with my bikes trying to sort them out

Well I have one just as nice if not nicer , and its a bit earler too, but I not riden it much this year my knees are playing me up. and there real pain full from time to time, so it sat on my bence chopping at the bit waiting for me to take it out for a good ride, but this weather not been that good at weekends , or iam busy with something else , I do live on my own so there allway something need doing,

yours Anna J
