Ceramic Doorknob Capacitor HT-57 Series - 1.187" diameter x 1.89" long - 
200pF, 15 KVDC rating.  Two are available - they are brand new, still in 
original wrapping.  They are direct replacements for the doorknobs on the 
Butternut 160M coil for when you blow them (and you will).  Butternut used 
to supply only 10 KVDC rated doorknobs on the older 160M coils (much easier 
to blow).  I bought these brand new from RF Parts as spares but I no longer 
have my Butternut.  Buy mine for $35 for one, or the pair for $60.
