Notice shot gun shell being used as a heater in the 2nd picture.
Very interesting, always find something neat in old books and magazines. Thanks!
I have that Poly-Choke booklet. Ordered when I was a kid. Tom from MN
As a kid I’d take fired shot shells, fill them with re-melted candle wax with a piece of string for a wick & use them to start fires when we slept out in the woods.
