Hemmi 149A

This rule is a close cousin to the Post Versalog 1461, the pocket-sized version of the full-size Versalog. Bearing a somewhat different scale arrangement than its Versalog relative, it's a wonderfully well-made and attractive instrument.

In a departure from the more common practice, the 149A's trig scales are referenced to the CI scale, not the C scale.
