Good question on the brakes. Do I need to pull the hubs off to tell the difference? (see photo). Also did '49' have the knee-action shocks?
Going by suggestions, I agree the best thing to do is not mess with the title and use the historical evidence if I ever needed to explain it's actual age.
Thank you all for your input - it has been a great help. Now to the process of the 235 swap out!
