If you have an American Sanders Super 7R edger, then it's time to meet grandpa. This is the Clarke Model C-5, shown here in photos submitted by Woodchuck Flooring Inc. in Toronto, Ontario. The C-5 was built by Clarke in the late 1940s and early 1950s to sand stairs and small areas. At the time, it was part of a family of handheld machines, including the F-5 and the OSA. They were all discontinued in the mid-to-late 1970s. That's when the Super 7A took over. Eventually, the 7A was replaced by the 7R, creating a third generation.
