3-part paper can???
Millions of Twist-Lock "FP"-style electrolytic radial capacitor cans were manufactured by Mallory from 1940s to 1980s.  CDE bought Mallory.

Antique Electronics Supply in Arizona bought some of the Mallory production equipment to mfg. replacements for the audio, guitar amplifier, musician marketplace.

I never replace this cans. I leave them for looks, and cut them out. I then replace them with 3 electrolytics with the negatives tied together, and put them underneath. Much cheaper than cans.
