OK, can I do it all in one post?
The gun type spark shooter is vintage 60s. They were included in every carton of Cadwell product as a way for Cadwell to shed liability and provide a "safer" way to light off the pot of powdered metal and gunpowder.
Even came with an instruction sheet to wear gloves and turn your back to the pot while lighting.
Safe my ass!
Come on, sneaking the Hubbel Plugs into the picture of the BOM torch doesn't make them lighters. Now I gotta dig down on my desk and refind my porcelain Hubble Plug.
For the kids, those adapters were originally made so housewives could plug their new electric iron into the ceiling light and do their ironing since the ceiling light was probably the only electric outlet in the room.
They were also useful in houses first wired for electric where the only form of outlet was the Mazda Light socket, before the 2 blade parallel plug came along.
