Morning all. Does anyone have a spare starting dog? Its the short one.

Location: Devon

Steve confused by 'the short one' the 27 one you need should be 3" long over all and 1 7/8" from the nut were it touches the bearing to the end of the dog. Hope this helps Ian M

If this is a 1927 car it should have a mag engine, which can only have the long dog. I suspect it is a later coil engine (either the engine is incorrect or the car is later than '27) which has the option of two alternative short dogs.

It could have been modded at some time, in fact John Colman's famous Chummy was fitted with a Box dog and a pin fitted to the original starting handle when his pulley collapsed during the trip. Ian M

Thanks all. The thread is 1 and 3/8th length, thickness of nut 1/4 and dog around 5/8th. Looks like someone has tried to build up end by hard welding.
Yes, engine is coil ignition. I was told 1927, do not have much history at present.
