    Description

    Antique Keuffel & Esser 4092 Slide Rule With Brown Leather Case & Booklet.
    Keuffel & Esser 4092 slide rule. Good overall condition but does need to be cleaned. It has some discoloration and yellowing. The metal has turned green and the glass has a residue inside. The glass may also have a small chip on the underside. It is smooth to the touch but upon inspection with a magnifying glass there is an imperfection. The case it was in definitely shows wear and the leather buckle closure is broken off and one flap is missing and the other is loose. The case says Julien P Friez & Sons Baltimore USA. Included is a booklet that was found with the slide rule but obviously does not go with it.
    Please look at all the photos closely and ask any questions you may have.
    Thanks for looking!
