The Surplus Store That Will Not Die is still gasping and I saw a box with a few hundred never used "postage stamp" caps of all kinds & sizes & makers. Bought a dozen of the larger sizes for testing on the assumption that bigger caps will be the ones most likely to be bad (larger ones are more likely to be paper instead of real mica). All passed like new on a Sprague TO-5. 
Soooo... is there any point in snapping up the whole batch? Would anyone want any of these?

What's the current thinking on cap replacement in these receivers? I wouldn't trust the 75-year-old electrolytic caps in the power supply or the Micamolds located throughout the set, but what about the oil-filled bathtub caps? Do you replace them as a matter of routine, or do you wait until one of them acts up?
The triangular piece of metal attached to the Vernier knob has some rust. What do you folks use to clean and shine a piece like that?
As always, thanks for your guidance.
