WWII fire control 'computers' - side note

Hi, A bit (er, lot!) of a long shot this, but it's probably vaguely on-topic... Does anyone know anything about the mechanical fire control computers as used in second world war for UK coastal defence batteries? I did some restoration work out in New Zealand earlier in the year on a wartime coastal battery which was built to a British design, and used British systems. Unfortunately all information on 'out' plotting-room computer mysteriously vanished in the 1950's, and the unit itself sadly was cut up for scrap value many years ago. It'd be nice to get some information on possible units though just for something to show on site open days. It's possible that the unit shared a lot of commonality with ship-based systems, in some cut-down form or other, but I haven't yet located anyone who can confirm this. I seem to recall a few posts about US equivalent systems a few years back, so there's probably a few current list members who are interested in this sort of system despite the units being non-electronic in nature! cheers, Jules __________________________________________________ Do You Yahoo!?
