Here's a picture of one of the bigger ones.
http://allstateguy.tripod.com/Those were a rebadged Puch 2 stroker. The bigger ones had 2 cylinders sharing a common combustion chamber. When I was saving up for my first bike, I used to sneak over to the motorcycle page in the catalogue when nobody was looking.
There was also an Allstate car, a rebadged Henry J made by Kaiser Fraiser. Now, the closest you can get to that good stuff is a bloody lawn tractor. They used to have a Silvertone TV with a strange feature. It had a jack in the back to plug in one of those little RCA 45 RPM phonographs. You would turn the tone control all the way anti clockwise to toggle a switch over to phono mode (shut off the picture and TV sound) and all the way clockwise to toggle back to TV mode. I used to have a lot of people comming into the shop insisting that their picture tube had gone bad because of that switch.
