Hi Alan,
I built a working home made replica a few years ago which works fine. Quicker than a calculator with practice. Usually accurate to 10'. Designed for easy quick aviation navigation.Not as accurate as the Bygrave but quicker and easier.
Details attached.
Best wishes and seasonal greetings.
Francis
