11 cab CMP Distributor question

[Tony Smith]

That is not an original 11 Cab distributor, it is called a 59A and was fitted to post-war engines from '46 to '49. Due to it's distinctive cap, it has the nickname of "Rabbit ears". The distributor itself is essentially the same as the '42 to '45 "Crab cap" distributor. The original type was a 3 bolt "Diver's Helmet".

I am not sure exactly what you mean by the rest of your question. Are you asking if there should be electrical continuity between the inside terminals on the cap and the outer sockets where the Ign leads fit? Certainly should be!
