This early small pocket slide rule slide rule measures 15 cm or 6 inches long, made from wood. It comes in the original card board box, signed with the number 37. It has the optional cursor placed at additional cost to the original buyer. This special cursor features a magnifier and was used on only a few models since it also has an indicator on the side. The slide rule itself is in good condition with some signs of use and age (mostly that it is a little bend). Priced accordingly.
