Excellent condition rule, complete with improved cursor, and very good, orange sewn leather case and belt loop.

12"/10" Full Size System Rietz Mannheim Slide Rule. Nestler's most famous Mannheim rule, the same kind used by Werner von Braun and Albert Einstein. This rule has a mahogany core, with white celluloid faces, black, and red filled and engraved scales. Has the Rietz over-range scale extensions. This is a later production rule (R/3 revision), and in excellent condition over-all. Scales are unmarked. Glass 3 line cursor. 2-part black paperboard case in good condition. Pics ARE NOT the exact rule for sale, but look very similar, some additional scuffs on the box in this example for sale. This simplex rule has cm side rulers 1:1 and 1:25, (great to leave parked on your desk!), all standard front/rear scales, inner body ruler extension, and conversion tables on the rear. Enjoyable to use, and very lovely to look at. I think is one of the most classic and attractive German designs, and this example shows those features beautifully. |
