Got a box 'o junk, and among many other things were these. I can't figure out what the 1 on top is.
Second one down is some sort of lamp?
And the silver thing is?
Second photo (img430) is the rest of the sort-of unusual stuff I found, just different types of resistors mostly, a different kind of fuse and cap too.

Top is probably a small signal diode.
Next is a neon lamp bulb, probably NE2. Commonly used for 120V indicator lamps, indicating fuse holders, Fender tremolo roach. Needs a series limiting resistor, typically 100K to 220K if used across 120VAC.
The silver thing looks like a thermal protection device (switch or fuse) that is commonly found in small high current appliances that have a heating element, ie, cheap coffee pot, hair/blow dryer, curling iron, etc. Usually have stiff, heavy leads.
The green thing looks like a cheap, low voltage capacitor.
Any writing on these devices would be a good clue.

Yep, it is. It got in the pic by mistake. It was just those 3 items that were bugging me.
The rest are mostly all resistors, there is a (I think) pigtail fuse that says 2V4, 145A. The 6th down is a resistor, around 10K. Guess it mounts in a PC. The 2 near the bottom that look like caps are also resistors.
I had fun digging through the box and sorting stuff out. Musta been 100+ cc resistors (unused), a big relay with exposed coil, and a new'ish transformer, pretty heavy. Plus lots of "filler".
