Much burning of fingers later and the repeater head is mounted on a pole. The photographs showed ladders up the front, presumably for cleaning the glass, and the rear, for access to the bulb. The signal will be operated by a servo so the operating wire terminates in a little sprung plunger which is a bit of 3/4 inch long tube beneath the base.
I've got to admit I'm quite pleased with the result and it will be nice to have a feature 'on scene' to demonstrate the aspect of the 'off scene' starter signal.
Thanks to everyone who pointed me at different resources for drawing, photos etc.
One last question.... Is the colour right? The photos I have are all modern and show the repeater, post and ladders all in grey like a modern colour light signal. However was this always the case? In earlier times (say 1960's) would the ladders have been black as they were on traditional semaphores?
