Mystery tube

[Mike Morris WA6ILQ]

One of my dads old stories was that when he was a kid his ham TX
had a pair of 45s (he thinks) in push pull with the bases removed,
mounted upside down and submerged in oil.
He claimed that as long as you didn't keep the key down too long
you could run 20 or 30 watts of CW.
