Oh that's good.

Mostly thinking of the future because I am primarily getting tools to use, not display. Currently it's some foreign stuff:
I have a Rotary Razor Plane from Japan (pic related) that has one packet of blades and the only supplier with more has a limited stock as the company is defunct.

A 1930s hand-cranked german drill press - the chuck works, but badly. Its on a nonstandard threaded rod and is keyless. I am unsure what parts are bungled but if it's more than a spring I will be fucked. Also paranoid about accidentally breaking a part and ruining an antique tool with a much more difficult ability to replace it without an intact original.

An adapter for a brace drill that has a 1/2-24 threading and only a 1/4" capacity keyless chuck. The shank is worse for wear and it slipped a few times already, so I want to get a spare made in 1/2-20 or 3/8-24.

A 3/8" socket to 1/4" hex adapter to use hex bits with a ratchet, speeder handle, etc. One came with a tool I bought and it's immensely handy, but I can't find additional ones anywhere in my searching (it only comes up with the reverse, that lets you use sockets with a driver) and the tool loses a primary function if I lose, break or wear out the adapter (it holds the bits with a friction-fit, not magnetic).

Bought a weird Japanese "rotary" plane off ebay. Going to clean the rust off the metal parts and have my friend translate the manual (just a sheet of paper) later.

It's not wood, it's plastic made to look like wood with a metal sole that is in pretty good condition considering the rust on the top parts. I think it's called a razor plane? Since it does not have a full, proper iron but a smaller blade. There's a little storage compartment with a packet of spare (non-rusted) blades and a shitty hex key for the screw that holds the blade and cap iron. It doesn't fit in with all the rust in the way, but it's a thumbscrew so it doesn't really matter.

No idea how old it is - there's no contact info on the instruction sheet and searching for "rotary plane" gives me jack. I'd guess late 80s as doubtful earliest, probably at least mid-90s or early 2000s.
