Here's one that came up on Ebay -
An original Estes Electro Launch from around 1964. That would make this one 50 years old.
There were no plastic launchers then, everything was made from pine and pressed board.
The main battery box body may have come painted red from the factory. The later, first plastic Electro Launch systems were molded in red.
The lead wires were the thicker brown "lamp" wires, very common in hardware stores back then.
Notice the asbestos pad "blast deflector" on the top.
On the side was a rotating panel. You can see the holes for the four "D" size Photoflash batteries.
Close the panel and contact was made with the battery end terminals.
The launch "button" wasn't much, but it worked!
Simply press down the spring steel strip and close the contact to launch.
I did bid on this one, up to $27.01
At the end, bigger bids were made. The unit sold for $220.29!
