Cylindrical Grinder pink aluminum oxide wheels 16"x2.5"x5"

Very large grinding wheels purchased from a closed machine shop. Originally from a cincinnati r78 cylindrical grinder, but should fit other large grinding machines. 16" diameter, 2.5" thick, with a 5" bore. The balanceable arbor has a bore of 2.365". These could make an amazing homemade wheel knife sharpener setup, or could be cut down into smaller wheels. They are extremely high quality pink aluminum oxide, good for carbon steels. Asking 100 for the used wheel, 150 for the brand new one, and 75 for the balancing arbor. Open to offers on the whole lot, and also open to trades for other machining stuff, mill tools, lathe tooling, precision measuring tools, welding stuff, etc. Feel free to ask, worse thing I'll say is no.
