Built a light up working radar monitor with a transparency slide graphic. I was all set to fit until I was given some detailed pictures of a Loyal wheelhouse which doesn't have this style of radar monitor...oh well! Isn't it always the case though, you search and search for reference material and find nothing, then as you've gone with what you think should be in there you end up finding (or being given in my case) some super detailed photographic images and start ripping the model to pieces again!
