Recently picked up a 3C. Model 1803 and serial number 209. Runs great and very tight. Has Craftsman variable speed motor and is mounted on a metal cart of unknown origin. Only tooling is one 3/4" collet and a boring bar. Collet it a bit odd in that it is the correct 1" diameter but 3.369" long instead of the 2.906" I have seen everywhere. Working on retrofitting R8 collets to it with a homemade draw bar. Pics to come if I can figure out how to add them.
