Found out my dad's old Coleman stove has a date stamp, and it says 1978
I was cleaning the burner on my dad's old two burner stove last weekend and found a little stamp on the bottom that I had never noticed in 20 years of using it. Turns out Coleman put date codes on these things, and mine was made in 1978, which means it has been on family trips longer than I have been alive. Does anyone know a good place to look up those codes, or should I just trust the stamp and stop poking at it?
