One thing I take for granted, but has to be unusual, is Victorian crucibles. Mostly they're in bits, but I have several complete ones, and there are still one or two places where the stream bank is built out of them. They vary in size, but the average must be about 18 inches high; occasionally I come across lids. They have to be from the local factories.
I have dug up quite a few long thin cast iron objects but don't know what they are :-\
