47 V8 ignition mystery

[Brian]

I don't know if this has any relevance, and I only heard about it through a mate, an old friend, very clued up with flatheads, I respect anything he says, so take it for what it's worth.... His experience was with a new adapter plate for early distributor, the top mounted plate that replaces the original coil. He told me the centre carbon brush was made of plastic!! I know there's a lot of shonky repop parts out there, Craig, is your centre contact in your cap actually carbon?
