Check the listing for details. Frederick Post Versalog 1460 Engineer Slide Rule Belt Case *GREAT COND*. Condition: Used, Made in Japan. Listed at 40.00 USD. Frederick Post Co 1460 Versalog slide rule with serial # 108 010, made in Japan with bamboo by Hemmi Seisakusho. Ruler is in great condition! There is some light yellowing on the ruler. Ruler movement has no sticking points to it. There looks like no physical damage to the actual bamboo—no knicks or cuts. Comes with a leather case with a fold over top that slides into a strap to keep it closed. Back of case has a leather belt loop strap so you can wear it. Case does have some rubbing wear on the corners (you can see it on the pics) and there is wear on the inside lining of the case (from the ruler being pulled in and out). This piece is in REALLY GOOD condition since it was made produced somewhere in the 1960s. Really nice find!
