C10 motor with OHV upgrade, but the chassis was more or less unchanged until ’51 when a plunger rear end was bolted on to very little effect. Clutch slip on early models, but all upgraded by now. Gearbox can explode. C11G was available as a 3 speeder with rigid frame or 4 speeder with plunger frame. Both had better front brake. Most left on the road have chassis upgrade to safer spec and not too bad as mild all-rounder.
