50 odd years ago I found dumped on some waste ground near my house what I would later learn was an R1155 chassis . No case or valves.
I set about dismantling it, imagining I was de-fuzeing a bomb or something.
I particularly remember opening the metal clad capacitors and unrolling yards and yards of paper and foil strip and getting my hands soaked in oil
Later, I met the guy who must have dumped it, although he didn't admit to it, he was an amateur who lived opposite the waste ground, and he became my amateur radio mentor.
