Standard type end used on BTH magnetos including the KC1, KC2, KD1, KD2 and KDV models. These would have been found on many bikes including the Rudge.
 
We also have the competition type castings as fitted to Nortons and Velocettes available if that is what you are looking for.
 
Cast in LM25 aluminium and heat treated, these castings machine very easily.
 
PLEASE NOTE: What you are buying is a CASTING ONLY. They will need machining before fitting, this will involve turning operations as well as drilling and tapping holes.
