A little off center but remember the 5" X 5" X 2 " selenium rectifiers used with alternators in the 1950s ?

Never saw one
Do you know which cars there were used in?

Those were aftermarket Leece Neville alternator systems, I was given one of the alternators that had been on a truck. It was going to be part of a standby power system of mine. The problem was that it was BIG, and quite HEAVY and difficult to mount. So I sold it cheap and located a much newer automotive alternator rated 100 amps instead of the 60, with internal diodes and half the size and weight.
And certainly this is FAR OFF the topic.
