-SG- The Norton four speed cross over box was fitted in the second half of the twenties Models 14, 24, 34 and 44. By all accounts it worked well, with the external kickstart mechanism being a weak point. The original patent application was made by the company and Arthur Carroll in 1924. Leon 'down under' has turned up a spare box which he does not need and anyone interested can send us an email and we will send it on.
