Default Help Identifying parts

I ordered a bunch of grab bags so that I could replenish my inventory in the workshop.

Most, I can identify but there are some that I have little or no idea what they are or just want to know a bit more about.

here are the first set of pictures.
I'm assuming these are some sort of narrow band RF filters? They are sort of heavy, feels like a sort of solid chunk of metal/ceramic.

These look like tuneable filters? or crystal oscillators that can be fine tuned?

These I think are also some sort of filter too? Seems to have a little more pins than regular crystal oscillators.

We like caps, so here are some found along in the pile.

I can identify the Wimas, the others all I know are just caps. If they are any good for audio projects, would be nice.

The white Rifa ones are interesting. They appear to be low tolerance parts as the value marking suggests.

These resistors I found in a big rack mount equipment. It has a bunch of cards with these precision resistors.

Would they be nice for audio use? Thinking of using them in the feedback loop of amps.

The blue circular component among your capacitors is a varistor. FYI.

thanks! for some reason, the numbering made me think it was a high voltage capacitor of some sort.

here's more, The Fujitsu brand IC (lower right) is described to be a dual op amp but no datasheet found yet. I think the top left device is a DIP packaged crystal without an internal oscillator?

The others, no idea.
