    Bill Morris' MHR1 reproduction
    From: Art Leung
    Date: 2021 Jun 11, 16:58 -0700

    Hi everyone - Bill Morris was kind enough to send me his MHR1 reproduction (German version of the Bygrave Position Line Slide Rule) and I had a chance to give it a try. I wrote up a quick report on it, a bit of history, and a test run using it and Bill was kind enough to put it up on his blog as a guest post  

    I hope it is an interesting post for the large brains of this group.
