Two West Virginia Swirls on the left, followed by a Marble King Rainbow in the middle, then two Peltiers. The far right Peltier is a Rainbo, the style of marble which started being made in the mid-30's and continued through the 60's.
The green and white Peltier (2nd from right), looks a little earlier. I think it's from the National Line Rainbo era, which went from the late 20's through the early 30's. Possibly from the later end of the NLR era.
