I have used this oscillator as an approximately 100MHz driver for an electrodeless lamp. It is supremely reliable and puts out several watts of power:

However, although grateful that it worked (using a transistor that is now only made in Russia), I could never figure out what actual type of oscillator it is and where on earth the tank circuit is lurking.
I have asked some quite learned EEs this question and they have all given answers but none really convincing - please assist.
I have also posted elsewhere for advice on a replacement circuit using an MRF136 - the Russian transistors can't handle the same power as the old 2N3375s.
