thanks for the answer. Well the thing is, that my Norton is matching numbers june 1940 year of manufacture, but was rebuild according to the plate on the toolbox on 8/4/1944. So my Norton is a mixage of the later production parts, but was born quite early. In this case any pre-44 handlebars and features would be good for it.. much better then the todays whatever-it-is. Donť you know about some suitable parts please? The handlebars can be found on Ebay, from GB and from India.
Originally I was thinking about rebuild the machine to it's "born" look from 1940's, but I think to remove it's re-build plate from 1944 would be a sin.
So the final look will be the 1944.
