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

I no longer carry them because I passed them on to my son and grandson but use to carry them all the time until recently… it was my Tilly lamps… one from the 50’s made in the UK that my dad used and passed on to me… it was the De-Lux versions of the X246 lanterns, that had a chrome plated brass tank and one I bought in the early 60’s made in Northern Ireland… great Lamps…
