Staedtler-Mars 544A 12″/10″ Simplex Slide Rule (NIB)

USD $65

A visually beautiful rule, complete with 2 part plastic case and factory box.  The 544A features the trademark S/M blue slide and body braces, multi-line (5 line) cursor, plus two color (red/black) scale markings, and folded scales.  The rule is self documenting on the right hand side for all scales.  Staedtler-Mars rules are highly requested but quite uncommon in North America, and are very well made designs.  Attractive blue slide and body braces, complement the bright blue and white two part plastic case.  The folded scales are especially useful for mark-up/discount calculations, and a center index is well marked for this.  The ‘invisible brace’ style with braces on the back gives the rule a very clean European look from the front.

Blank on the reverse side. These were still sealed in a factory bulk pack, so everything is in mint condition.  We have included reprints of the S/M consolidated rule instructions because these came factory packed with no instructions.
