Posting the message below for a non-subscriber (thanks to Bruce Damer) - please reply to Patricia Gray at the email below. And here is the Digibarn's Comptometer Page: http://www.digibarn.com/collections/calculators/comptometer/ Lawrence === I have what I think is a model J comptometer - but the red or white key in the upper right hand corner of the number keys is missing part of itself. We bought it at the San Jose Flea Market, sometime before 1987, when my husband died, but the local museum here has a bunch of them and no room for more. Thanks.
