Jeff Smith with his Ultra Rare 1939 M20 Gold Star Refittment

Here's Legend Jeff Smith working up a refittment of a 1939-40 M 20 which is one of only 16 in the world. The TT Carburetor was in a box from the early 1930's that his father had put away and stored until 2015 or so unused. HE treated it with USA Fluid and put it on the machine and was astonished to see how it just worked like new. Many details are given here on the collectable structure of these old machines. This man is a walking encyclopedia on BSA and Gold Star because he was the world champion for many years in a row a half century ago.
