Hey fellas, I picked up this old breakerless Mallory distributor. I’m curious as to what it is and how old it is. Was this originally breakerless or is this a conversion? The number on it is similar to the old ZC/YC flat top dual point distributors I’ve had except this has a “P” after the ZC. I’ve done searches on that number and don’t see much at all that can tell me anything. Is this even worth messing with? Sent from my iPhone using H.A.M.B.
