I just acquired an unusual razor. It just says "Mond" on the underside of the baseplate, and on the case. It does not say Rotbart or Extra anywhere, no markings or engraving on the shaft of the handle. Instead, it looks like a ringer for the Gillette 1917 Old Type 460-B shown on Mr.-Razor, except for the fact that the word Gillette is nowhere to be found. The threaded shaft of the cap is loose and wobbly, and it's also wobbly where the baseplate attaches to the handle. When it's assembled, it's a nice snug , solid fit. It doesn't look quite like anything I can find on the web. Can anyone here comment?
