These are a number of power tools (mainly general purpose/woordworking) which are powered by a drill. The attachment include a table saw, jig saw, skill saw, drill press, grinder, planer, sander, and more.
The only information I have found on this was on the web at: http://members.aol.com/twade36577/wanted/early.htm I emailed the author, however it was returned "undeliverable". I would greatly appreciate it if anyone out there can give my some furthur history and value on a full set of six. There were eight, but two of the cups are missing.
