It is American made and one of the most desired collectors item. I've listed it as condition "used", but it is in its original box which is in a cardboard sleeve. It has not been used and comes with all paperwork and leather sheath. There are no marks or dings on the slide rule that i can see, but please use the pictures to look for yourself.
Includes items usually missing: the paper ring around the leather case, the care booklet, pocket rule catalog. Only wish i could include one of dad's pocket protectors. My father was an electrical engineer at pearl harbor, and my grandfather was a machinist there during the bombing.I'm sure that this was a graduation gift that my dad saved and never used as i've kept his working slide rules. I'm an electrical engineer as well. Info i found on the internet is below. I've done my best to try to find correct information about the product, but make no guarantees as to the accuracy of any of the information. Please do your own due diligence.
