The outgoing secretary got it off his predecessor. No one knows quite what it’s for. It comes in its own little pouch. In the top picture you can just see a little roller inside the bit that squeezes down, though it doesn’t squeeze down very hard.
We also got power! an official company stamp, in a weighty metal stamping machine that embosses the paper with the stamp design. I can remember something like it from my grandfather’s study and it has a wonderful Victorian steampunky sort of feel to it. That, I can work out. The squeezy thing shown above, though … still guessing.
