I dont know what year it's from but its old. The make is 20th Century Mobile Homes Limited based out of London, Ontario, Canada. The Model Number is 2S. It is a pop-up trailer that sleeps two comfortably but three. You put out each steel side for the beds and then manually move some tent bars in position while placing the canvas tent overtop. I can't find any information on this trailer. Any help out there? Looks like 1950's-1970's.
