Here's a real test for you. A guy I work with bought this at a local swap meet (local as in Brunssum, Netherlands) and brought it to me. I enjoy restoring hand drills, but to date it's been all MF. I assume this is German made, but no markings. I found it interesting because I couldn't figure out how it came apart...at first, and because the small gear was enclosed. The tab on top of the gear held the gear in place. Once it was removed (the flat round disc looking thing on top of the tab is actually a screw) it exposed the gear. The gear has a small screw holding it to the shaft.
The next interesting thing is the chuck. It's hard to tell from the pics, but it is a springed three-jaw chuck similar to a Parsons chuck. The interesting part is the shell is one piece. I can't figure out how to get the jaws out. If you notice on the side the shaft goes in it looks like a fat pin sticking up. The shaft has a hollow end that this pin sits in. From there it operates as a normal chuck.
The drill turned smoothly which is amazing considering how gunked up it was. The design is simple, but very effective. It's 10 1/2 inches long and the main gear is 3 1/2 inches. I assume it is a 1/4 inch chuck.
