Here we have a white porcelain insulator as used by our friends at the Algoma Eastern Railway which ran from Sudbury to Little Current, Ontario from 1911 to 1930 when it was taken over by the Canadian Pacific. This has the green ink under-glaze A.E.R. marking. There have been a couple of these sold in the past few years on ICON which had base damage but this one is near mint. That line you see from the wire groove to the base is not a crack but a rust streak from the tie wire. There is no damage that I can see so I will call it near mint. Price is $75 and I will pay half the shipping cost to the US or Canada.
