I've been looking into using oil washes on 28mm Historical miniatures and have found a ton of stuff on Fantasy/Sci Fi stuff in terms of tutorials/vids. Either my google foo is very off or the tutorials/vids simply do not exist.

I'm aiming to use them for The Crimean War, Ancients, Dark Ages and Late Medieval mini's.

Does anyone know of any such tutorials/vids using Oil Washes on 28mm Historical miniatures?
