Subject: Slightly off subject request for identification

A engineer friend of mine, who I have been trying to get to join the
list, has a piece of equipment he cannot identify.  I suggested that if
anyone could they would be on our list so here goes.  He has a tube(I
would describe it as a diode as it has only two pins) that is
cylindrical with a diameter of approximately 2" and length of 6".  One
pin on each end.  This is stamped in the metal on one end: VC50-20.  And
this is printed in ink near by: 48B081.  Now, it is mounted in a tank
circuit of some sort with a high voltage variable capacitor with blades
about 6" in diameter and the overall length of about 12".  this is
printed on the capacitor frame:  Barker & Williams, Upper Darby, PA,
CX70B.  Vic, my friend, has contacted them but they have no records as
old as this apparently is.  Any help would be appreciated.
