A recent purchase included a BTH M1-AX4 (c1930s). This is somewhat taller and skinnier than the normal M1 is anticlock from drive end and has a lovely fat spark. It also has fittings for cable-operated variable adv/retard (bike?). I had thought it to be for a Crossley lump but it seems not. Anyone know what it fits?? ttfn Roland
