    Re: Cylindrical Slide Rules
    From: Ronald van Riet
    Date: 2009 Feb 13, 09:42 -0800

    small correction: the HR1 was the German version of the Bygrave, the
    HR2 as depicted in the link, was a larger variant, specifically
    designed for maritime use, whereas the Bygrave and HR1 were primarily
    meant for aircraft use.
    
    Please read my article as pointed to by Gary LaPook.
