About the only thing that effects original tar filled model A coils is carbon tracks that extend up to the metal tube housing. Carbon tracks can short the coil but can be scraped off . Carbon tracks are mentioned in the service bulletins . Like Tom , Ive never had a problem with an original , even if it was beat up and rusty .
