My Westinghouse OV-15 Silverliner

175W MV, 240V, with 120V PC socket. Originally had a 240V PC socket but I rewired it for 120V so it would be like the ones that were used by my local utility. The date code on this puppy is "CK", which, if my translation from my GE date code system is correct, is March 1976 for Westinghouse (it's March 1974 for GE; I'm pretty sure Westinghouse used the same date code system, but delayed by two years). The ballast is very loud in this, especially for a single coil simple reactor ballast. It's in great shape though! Came from a municipality utility company in Sterling, MA.
