You're probably thinking of the oscillator that Marv Frerking
called a "grounded-base oscillator".

Alternatively, take a look at the Butler design by John Stephensen in
November/December 1999 QEX. He explains clearly why folks ever had problems
with Butlers and better yet, how to cure them. I've used this circuit
(without the Varactor tuning) on 9th overtone oscillators using hound dog
crystals.
