This is a vintage Fredrick Post Versalog Hemmi Japan Cat. No. 1460 bamboo GJ slide rule with the leather case. It is vintage circa 1950s and in very good condition. It measures 12.5 inches long without the case. The slide rule itself is in excellent condition, the case has a few scuffs, and the original owner name written in ink on the inside flap. The leather is still very strong and nice.
