I guess, as the fomenter of this thread--which has gotten even further OT than I ever thought--I could contribute this: I have a Lafayette Radio Log-Log-Decitrig rule, model F341, made in Japan, in perfect condition, which I used to use in the 1960's and early 70's, until calculators became available. I think it is made of bamboo, but it has a very nice plastic scale on both sides and the slide. I admit that I never understood all the possibilities of this fine instrument. It works as well today as it did when it was made. I don't! --doug --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
