    Hi George,
    I am a keen occassional collector of old nav equipment, especially slide rules, old octants etc. I would be very interested in the Poor Line of Position rule and anything else similar in your collection.
    Not sure what the regs are about this on Navlist? I guess it is not a buy/sell market place? Perhaps Frank would advize? I got most of my stuff on ebay.
    Out of general interest, have you/ anyone details of the Poor LOP rule and used it to reduce LOPs? A 14" circular rule means pretty long scales to provide reasonable accuracy? But probably not so good as the Bygrave? Any thoughts Gary?
    Anyways, good luck with whatever you decide George.
    Best wishes
