Looking for photo etch engine screens or CMK resin for Tamiya King Tiger

Not sure what options or the best but wish to buy a set that.

No problem! Aber, Tamiya, Eduard all make them. Probably also Voyager. You can try searching Mega Hobby, Sprue Brothers, BNA Model World, Hobby Linc for starters. Tamiya I know makes a fret with just the screens. The others may be a part of a larger detail set.
