These things rock, Bud. I have a wall at home in the museum room called 'the wall of knives' with big copper & slate switches like this. Biggest one is about the size of this one, but a three pole, double throw. Drove by an old mill/machine shop one day and they were ripping out all of the belt drive pulleys and other goodies from days of yore. Sitting on top of the pile was the switch. Asked one of the workers if I could have it, to which he replied "I don't think anyone will miss it" and it leaped into the bed of my Land Rover. Solid copper, inch-thicks slate base, h-e-a-v-y.
Eventually the permanent radio room will get set up with open wire feeders and all, allowing some of them to actually get used!
