“Metal shards inside the shower head of the place I’m renting? What are these, and why are they in there?”
“Surely they are solder from copper plumbing. If you overheat the pipes while soldering, long strands like this can form on the inside. Definitely a sign of improper soldering, if that’s what they are.”

Abijah,
Not so much as a stamp, as a printing plate. Before ink jet printers, they would ink these up, and press paper against them.

Abijah,
The dial on the right sets the resistance in Megaohm as far as I can read. If I see that correctly its the printing plate for manual for an old X-Ray machine. Only those kathode tubes (at the bottom) would akquire such high voltage (200V)
