[Amps] Looking for Door Knob Capacitor

[Ed Hatcher via Amps]

I am in need of a 220pf; 250pf; or 270pf, rated at about 15kv. Would also consider several 50pf. American made only.
Thanks and 73, Ed-kv5i (eh_54 at yahoo.com).
P.S.
Is there anyone out there that knows me and is going to Dayton that would keep an eye open for any of the above for me? I could send by PayPal or a USPS money order?
73,
