Two screw caps. Zinc/lead. Octagonal one looks like zinc. Round one looks like lead. The octoganal has a faint letter F and the round one has a visible 5.

The round one resembles a base for an old style screw-in power fuse. I’m not aware of them ever being metal though. It would be a hair curling trip if you forgot to throw the switch before changing fuses. ⚡️

They look like lids to black powder tins

I would say both are caps (lids) for black powder cans. Black powder granules are sized by the letter F ,FF,FFF, FFFF.

Agreed. This is exactly right.
