While I’m thinking of it I want to ask what kind, if any weathering would have occurred on our ships ( mostly interested in the DEs) operating in the Atlantic during the early 50s?

Well Jacob, that's a good question, mate. . .
Ship husbandry, one of the most important duties of the crewmates, is now, as it was in the past, because what happens if you don't maintain your machine?
There are some minor elements of weathering (light washing to bring out some detail,a bit of drybrushing to show some water run-off smut, and maybe a little rust around the ol' anchor hoist) but for the most part, weathering is non-existent because of the strict husbandry practices.
