For all the people out there looking for additional parts....
Try and get your hands on 1/600 scale Waterline models. I know of 2 or 3 companies making WW2 models, eg. Tamiya & Revell (I think) that are a GREAT source of anything from antenas, to radar-arrays & off course various pieces like Gun turrets & emplacements, torpedotube launchers etc.
Also there carrier models normally come with assorted planes....... some snipping & scraping will get U your fighters & bombers........
Current project underway is converting a Chaos Cruiser model....... & the main ingredient is a Nurgling base......
