Late Shipley and Brum Scotts were fitted with roll on centre stands. They did vary slightly in width. Some late Shipley Scotts had clamp on lugs and some were brazed. The lugs served 3 purposes, support for the rear brake crossover shaft, rear support for the gearbox tray and for the centre stand.
I made up lugs for two of my prewar Scotts as being in my eighties l found hauling the Scotts onto rear stands too much effort.
