Mallory Model A distributor, Model C, type11
 

Hello. I have one of the first Mallory, dual-point distributors for a Model A. It is cast to take the original large armored ignition cable, and the moveable upper points plate has the short arm to connect to the steering column rod to retard or advance from the steering wheel area. The centrifugal advance weights are controlled by numerous thin leaf springs(almost like feeler gauges) for each weight. Should those sets of springs be exactly the same for each weight? Also, are there any parts available, or substitute parts available, distributor caps etc. for these models? Thanks for your time.
