I came across this web page, a collection of old photos of everything. http://www.shorpy.com/
Maybe someone else has listed it but it is worth another look, just refer to the Photo Gallery on the left hand side and click to the subject you want. Have a look at Shorpy himself, an interesting character for a mine layout.
Welcome to the forum Les. Yep, Shorpy is an inspirational standby for many modelers. As you go along, you'll find many more.
