VINTAGE KEUFFEL & ESSER 4081-3 SLIDE RULE w TATTERED CASE

Description

This listing is for a vintage 4081-3 Keuffel & Esser slide rule with it's tattered old case.  This piece is in very good condition with minor soiling and one stain on the edge that will probably clean up.  I haven't tried to clean it, selling it as found.  The case is still doing it's job, but it's torn at one corner, and it's in terrible overall condition.  The glass and slide in the rule move freely.   I have hundreds of antiques and collectibles listed in my eBay store in categories for browsing convenience. All of my items were found in estate sales and cleanouts on Cape Cod.  None of the items have been touched by the public, just stored in totes. All items have been stored for weeks or thoroughly washed.  I am in a low risk area and I am observing all precautions for virus protection.
I use USPS for shipping, usually Parcel Select or First Class. All international shipping is done through eBay, no exceptions.  I pack everything thoroughly, using well packed, sturdy cardboard boxes.
