What is the oldest thing you take with you camping or rving?

I take a lightweight sleeping bag I bought in the late '60s and a tent and stove from the early '70s.

If out at a cooler time of the year, then it is probably the medium weight dacron filled bag I bought in early 1950s or my wife's similar bag a few years newer. Or maybe it is the Boy Scout mess kit which might date to 1953. Or a knife of similar vintage. Some of this stuff just does not wear out.
