The Mars 561 Version With A 1:33.3 Face
Staedtler Mars 561 98-2BK is the version 2 triangular reduction scale ruler: 1:20, 1:25, 1:33.3, 1:50, 1:75 and 1:100 across six edges.
Version 2 shares five ratios with version 1 but swaps the 1:125 face for 1:33.3, a step that sits between 1:25 and 1:50. If your drawings or course briefs call for that in-between ratio, this is the only Mars 561 that carries it, and it still stops at 1:100 for general plans.
The six ratios are printed down the blistercard, and Staedtler publish the same set in their Mars 561 reduction scale table. The body is solid white plastic with coloured grooves marking the faces, and the card carries Staedtler's Made in Germany mark.
Staedtler Australia do not run a web page for this version, so the scale list here comes from the card and the scale table rather than a product page.
