Well... I was born in the late 1940's.
Some things I recall having were Lincoln logs, I had the plastic bricks with the windows & doors you used to build houses, and I had an erector set. I also had Lionel trains. And I had a chemistry set (the smaller one they made at the time.) As a kid, I was very hard on my toys. Over the years I busted them all up, for the most part, and the pieces went to the trash.
One other thing I had was a machine gun! It sat on a tripod and shot rolls of caps. Plus there was a red tube at the end of the muzzle that moved rapidly in-&-out when you fired the gun to simulate flames coming out of the barrel! What a toy!
