A little update on progress. The window issue hasn't been solved yet but I'm busy working on other details. Here is a composite shot of some of the details I'm working on.
The jury is still out on the KV Models radiator core. The etching is very nice! There are some valid concerns about it blocking sound. Until I get to the part of the build where I fit the speaker, I won’t be able to make my final decision. In the meantime, I went ahead and did some finish painting on the KV part. I spray painted the core a base dark brown. After this was cured, I dry brushed silver over the entire part to force a contrast in the texture. On top of this, a dry brushed a small amount of light green around the lower edges of the cores to simulate brass corrosion. A little update on progress.
