As I mentioned I also use the train table to assemble Erector models. These pictures are of some of the larger Erector models. They are all of the Amusement Park series from Erector sets from the early 1950s. The Merry-Go-Round was made from no. 10 ½ sets and the Ferris Wheel was made from a number 8 ½ set (from a 1952 set in a cardboard box - cardboard because of Korean War metal shortages).
The Parachute Jump was made from no. 10 ½ set.
These sets are an impressive sight when they are all operated at the same time.
