Up for sale here is this NOS vintage General Instruments (probably made by Micamold) paper capacitor, dated 1963 and Made in USA.  It is marked 16 uf 450v, but tests higher and shows some voltage leakage, so you'll probably want to restuff it.

US shipping and handling is $6, and international is $20, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.

I have more capacitors and other vintage electronics listed--feel free to take a look!
