Vintage Frederick Post Versalog 1460 slide rule with Hemmi bamboo construction. This is a quality engineering tool from the pre-calculator era, made with natural bamboo body and metal slide mechanisms. Comes with the original leather case.

The slide rule is in used condition with visible wear consistent with age and use. The bamboo has some patina and the metal parts show signs of handling. The mechanics still function, though I haven't tested every scale extensively. The leather case shows creasing and wear but holds the rule securely.

Slide rules like this one are sought after by vintage tool collectors, engineering students, and anyone interested in mechanical calculators. If you work with vintage instruments or want a functional piece of calculating history, this is a solid example.
