Up for sale here is this used vintage Sprague Atom capacitor.  It is marked 10 uf 450v, but may have drifted over the years.  The paper covering some damage.  This is untested and sold as-is.  I would recommend bringing it up on a Variac.  Please see my pictures for details.

US shipping and handling is $4, and international is $14.  I accept Paypal.  If you have any questions, please ask.

I have a number of other capacitors, Magic cards, and vintage electronics listed--feel free to take a look!
