I answered a Kijiji ad tonight for 2 wooden planes for sale, at $25 each. I knew I could only afford one, and after looking at the two, selected the one I wanted. It needed a bit of planing on the bottom, but was in overall better condition than the other. So as I was reaching for my wallet, the nice man said, "What about the other one?" I said I really couldn't afford two, and was interested in using them, not in displaying them in my rec room. He said, "OK, how about $30 for the pair?"
Ka-CHING! I gave him the $30 and came away with at least one restorable plane. He says they were his grandfather's. The blades have chip breakers, and are about 4 to 5 mm. thick. It will take a bit of grinding to get the rust off, but I should have at least one usable plane out of the two, maybe two planes.
Pictures to follow.
