1882 Ke Thachers Calculator Thatchers Slide Rule

This is na antique 1882 k&e thacher's calculator, or cylindrical sliderule. My father askde me to sell it on ebay for him. It has been in his personal collection wrapped in plastic for over 20 years. It is ni good condition for its age. Pay attention to the photos which show the crack in teh drum.

The carck interferes with rotating the drum inside the cage, but not with left to right sliding. I've taken five pictures. Ask for more if you need them to make bidding decisions.

There is no box or manula for this device. It will be shipped in many layers of bubble wrap with the necessary insurance aplpied at my expense. Buyer pays shipping, via su postal service. Priority is optional, ground is uusally less, but slower. There are two numbers on the back board. Watchers tell me the larger number (4012) is teh model number and the smaller number (1516) is the serial number. This doesn't seem to show well in the photos. My photos are higher resolution and were down scalled by eaby when uploaded. Ask for the orgiinals if necessary. Slaes to continental us only. Paypal only.

Aks questions early please. Happy bidding.
