EW 1926
Does anyone know the thread used on the 3/8 stud on the gearbox adjuster?
one end should be fixed into the casting in some way and the adjuster screws on the other end
it looks like its 19 tpi not 18 or 20 and knowing the strange threads used on the Bristol wonders I would rather not jump to 3/8 BSF without double checking the thread form
