I've managed to recover some of the tutorials from the defunct Simmer's Paint Shop. If anyone wants them I would be happy to upload them. I've also been busy re-creating the Photoshop color swatches based on the color charts once found on the site. At the moment I have completed the majority of the American colors except for the World War 2 US Navy. The Luftwaffe, RAF, Soviet VVS and Imperial Japanese Navy and Army ones are on the to-do list. See the saved pictures below of the old color charts from Simmer's Paint Shop.
I also have saved some tutorials and various resource files from the also defunct Screenshot World.
