re trig slide rule marked in degrees and minutes.
Just for information, the Fuller 2 cylindrical and Bygraves are so marked. Makes life very easy for certain calculations.In many ways,especially my adapted mini version of the Fuller with added cosines, I find them the "almost"perfect slide rules for celnav and with cheap, easily obtained plasic tubes and pipes, easy to make with only craft skills.
Details re builds on request.
