Erector Set c1950

My father just nabbed an old friend's mint 8 1/2 all-electric erector set, in a heavy red metal box complete with motor and instructions (copyright 1948). Remembering the smaller set he had, Dad's going to show my nephews how to make a giant crane attached to a magnet. "See all these things you can make?" our gleeful engineer says. No fear of electric shock when it comes to retro technology! After all, writes Erector founder A.C. Gilbert, "You are a lucky boy to get an Erector Set. No other construction set contains so many different parts ..." Boys and their toys.
