Ignition condenser

[Rudolph]

Hello I have a 1938 24 stud motor I adapted a crab style distributor to a wile back, I was wondering what mf should the condenser be and what make and model would I ask for when buying it?

I had a pile of used genuine condensers but all of them were bad, just popping and banging from the motor,

I fitted a unknown one and the car has run fine now for 2 years with no points deterioration but its too rusty to see any stamping, if only I knew the MF rating.
