Figure out what marks, mods, etc existed for this relatively common gun director. Figure out what modifications may have happened to it during its wartime service. Did it receive radar at some point? If yes, specify what kind, and if it isn't drawn - look through the
Catalogue of Electronic Equipment to find it and draw it. Draw the radar's side, front, and plan views. Find the specific antenna designation in the
Antenna Catalog and note it alongside your drawing.
Draw the side, front, and plan views (if possible) of the director itself. Identify any specific mark and mod for the optical rangefinder inside it. If the optical rangefinder changed over time, figure out the variants and include that. Identify any specific mark and mod for the director shield itself - if this changed, make a drawing for each.
Simple stuff guys. The old battleships are pretty well documented so you should be able to find all this if you apply yourself. You've all used my stuff (over which I spend countless hours researching) many times over, so now you get to return the favor!
