Hi. This is a proof slide rule in very good cosmetic and working condition. Please see all of the photographs. It measures 8 7/8" in length.

Please take the time to view the other items in my shop as there are often similar ones to this in stock.

I will combine multiple purchases for cheaper shipment.

Items that I put up for auction will never have a reserve on them. 

Please message me if you need any further information.
