What to do with 2N389

[Interference]

Hello,
I own a few couples of 2N389 transistors. They are new, coming from military surplus stuff.

From what I read online, it looks this is a quite old component, so I didn't find any project based on them.

Does anybody have some ideas / suggestion on how they could be employed?

cuff links or a nice tie pin !?
are these silicon or germanium?

Silicon.

That's a rare, historic transistor:

By today's standards it's probably pretty awful, electrically speaking.

That's what I thought in the first place 😱

Thank you anyway.
