Clean Lionel Late 91 Circuit Breaker(A)
Here is a Clean Lionel Late 91 Circuit Breaker, 1936. It is the late version with nickel cap. It lit when tested, but I wouldn’t use it as a circuit breaker without an upgrade, as they didn’t use modern standards for tripping(Untested). It is clean and shiny, showing light play wear, EX+.
