You are right
This Busy Bee is unique and was built by Mr J A Mills of Mansfield in 1919 for a total cost of £120; he then proceeded to use it as his daily transport for the rest of his life and covered over 100,000 miles. It was originally powered by a 4.5hp Stag engine but this was replaced by a 6hp AJS V-twin in 1928 and which is still used today. Drive is by chain to a mid-mounted Sturmey-Archer clutch and three-speed gearbox and thence by another chain to the single rear wheel. The frame is tubular steel and just ten bolts secure the three-piece plywood body to it. It is really a very small piece of automotive history.
