59 A good pair of large proportional dividers for use on maps while navigating. These would have been used by all services for plotting on maps etc. the dividers are in great condition just dirty and uncleaned, they are nicely marked with the WD arrow to one side. They are in their original fitted case which is marked G.A. the same marking is on the dividers and is presumably the makers initials. The case is in good order but the lid doesn’t quite lock down properly.
