Description: Vintage 1940s era Keuffel & Esser drafting slide ruler with leather case. Case has Bucknell banner sticker, along with two others that look like Purdue ? On the back. Name stamped on case front is Dave Schaffer. Same name is also engraved on metal piece in slide ruler. Marked Keuffer & Esser with patent numbers.
