Here is a rather obscure little Marx accessory for the collecting completists out there.  Everyone has seen the many METAL circuit breakers made by Marx to work with their trains, mostly prewar.  But this is one of the much harder to locate postwar PLASTIC circuit breakers that they made.  It is the #451 50 Watt Circuit Breaker, in black plastic and in nice shape.  By the time these came out, virtually all of the train transformers had a built in circuit breaker in them, and few people would even have a need for this item, let alone pick one up.  Many collectors may not even know about them!  This unit is in really nice shape, and I have photographed it from all 6 sides, plus the angle shot so you can read the lettering on top, with a yardstick in most of the shots for size reference.  A small item (especially compared to its prewar relatives), measures about 2 1/2 inches by 1 5.8 inches in size. No box with this one (if you are the type of collector who really needs the boxes, the only boxed example I found on the net for sale is available at the bargain price of $75 plus shipping!).  Priced reasonably, with only actual USPS Ground Advantage or Priority Mail shipping charged to the winner!
