    Re: Buy or build a modern Bygrave slide rule

    Hi Sean,
    I have built several Bygrave replicas a few years ago, all of which are easy 
    and cheap to make and work perfectly. The latest look and feel like the 
    original.All details on the archives, but can send you build details on 
    request.
    Best wishes,
    Francis

    Subject: [NavList] Buy or build a modern Bygrave slide rule
    
    Would like to contact [anyone] about buying/perhaps making a modern Bygrave 
    slide rule. My intent is to use it for practical celestial navigation. Kind 
    regards, Seán T. Rickard
