OS Swap Sheet
WANTED posted Sept/Nov 2008, Jan 2009

The Slide Rule Loaner Program at the International Slide Rule Museum (ISRM) is gaining momentum, made possible by contributions from OS members.  As you might know I send these out at my cost with no charge to the schools for up to a year at a time.

I need additional sets, one consisting of 25 log-log decitrig (wooden stocks prefered), K&E 4081/4181/9081/68-1210's (or Dietzgen's with similar scales 1731/1733/1734)
Front: LL01, K, A [ B, T, ST, S ] D, L, LL1 and Back: LL02, LL03, DF [ CF, CIF, CI, C ] D, LLL3, LL2

The other is a set of 25 Post Versalogs or Sun Hemmi/Hughes-Owens equivalent (I'm up to 11 now), so if any of you have extras that you would be willing to part with, they will be put to good use.

I did get a request for a demonstration rule to accompany the sets, but I had given the ones I had to the Computer History Museum. If anyone has any 4' Pickett's at a reasonable cost, let me know, and I can loan them out as well.

Thanks for your help! Send to:

Many thanks to Skip Zogopoulos and David Hecht for their generous contributions of SR's for the program. They join George Keane, Ted Hume, Tom Miller, James D. Clark, D. Boone and John R. Farley as donors.

I also want to thank Otto van Poelje (Netherlands), Dr. Klaus Kuhn and Peter Holland (Germany/Europe) and Robert Adams (Australia) for offering matching sets in their countries and hosting the program there through ISRM. (need hosts in England, Japan and Canada next).

 The latest schools recently receiving SR's 2009  are Hood College in Boston and South Brooklyn Community High School in NY. There are four other sets in use.

Let your local educators know about the program if you get the chance!

WANTED Jan 2009
As a consequence of my on-line exposure, I have been asked to help acquire/broker slide rules for other institutions. Peggy Kidwell, the curator of Math History at the Smithsonian is looking specifically for a Guedon and a Charvoz-Roos. I assume the former is the small SR made by OEM's by UNIS in France, and the later the pre- WWII version, when they made their own. She has also asked for a SR made in the 1700's. I've helped the Smithsonian with previous requests but I am now unable to provide her with these particular specimens.

 My company manufactures pottery products and we use a calculator (#2777) to calculate plaster usage for our molds. Our master mold maker is in his 70s and has never used anything but the US Gypsum plaster and cement calculator. Unfortunately, the one he has is worn out and US Gypsum doesn't have them any more. If anyone has one that they can give up, I would be very happy to trade some pottery from our web site.
Thanks.

I'm planning to update my original JOS article on the Load Adjuster with a listing of about 80 aircraft types for which load adjusters were made. The table will include plate numbers. I'd also like to include serial numbers. The serial numbers can be found on the edges of the adjuster's body and slide. Any serial numbers and the aircraft type you can provide will be most appreciated. I don't need the plate numbers which are on the face of each scale.
