Stowed away in a corner of this sub were some extra insulators - all modern to be sure, but that 34.5kV mud (which turned out to be Knox) was sure interesting - could not see any sign that it had radio treatment! Couldn't tell if it was a 2-part or a 2-skirter other than the fact that it had indeed been in service at one time (there was dirt in the side groove consistent with contact with a tie wire).
