Ok A little more info:
Top-left is labeled AH+H, top-center is Hubbell, top-right is smith+stone
Bottom-left is smith+stone (seems very common here), bottom-right, another smith+stone.
Second is a smith+stone, rather common around here. the third is a smith+stone, push+pray, I never seen these before. 4th one is a GE. No idea on the years of any of the devices other than what's mentioned in this thread
