Up for sale here is this NOS vintage Mallory paper capacitor, from the 1950s and Made in USA. This is marked 5 uf 450v, but may test higher and show voltage leakage. This is sold as non-working due to age. I would recommend bringing it up on a Variac, but you may need to restuff it. Please see my pictures for details.
