Sourcing the potassium nitrate and sulfur was no problem in the '50s but trying to grind down charcoal was a miserable task.

It wasn't much of an explosive but back then dry gas came in about a 12 ounce can with a conical top that necked down to a screw cap. Filling one of those and lighting it lead to a very satisfactory fountain of flame. I never thought to try launching a rocket with it.
