Thanks all. I sent the files to the university print shop and they can produce a 'sticker' for £2...

And here is the finished article. £160 for a correct era/make clock, images from @Drazyl @s_n_l_r & @R0B, £2 from the Uni printing shop for the sticker and a bit of turmeric in water to 'age' the dial.

May I ask what the theory behind it is? Easier to read from a distance?


it shows what colour shoes to be wearing/handbag to carry at what time of the day

Used in plotting rooms. Aircraft position was recorded along with the colour of the triangle beneath the minute hand at the time of sighting. This was reported to sector headquarters, where counters of the relayed colour were used to represent each air raid on a large table with a map of the UK overlaid with a British Modified Grid. As the plots of the raiding aircraft moved, the counters were pushed across the map by magnetic "rakes". This system enabled "Fighter Controllers" to see very quickly where each formation was heading and allowed an estimate to be made of possible targets. The age of the information was readily apparent from the colour of the counter. Because of the simplicity of the system, decisions could be made quickly and easily.

well there is always the sensible and accurate answer.

So H67 in the linked picture has been plotted 3 times within a 10 minute period (starting either at 10, 25, 40 or 55 minutes past the hour)?
