[Boatanchors] Need help identifying oscillator circuit

[Charlie Cheney]

Some time back I picked up a homebrew VFO front end (1.75-2.0 MHz). 
Mechanical construction is excellent, clearly shows pride of 
workmanship, but it would only work for a few minutes before it stopped 
oscillating. I've fixed that but in the process drew out the schematic 
and I can't identify the circuit. It's similar to a series tuned 
Colpitts but the output is taken from the screen (of a 6AU6), not the 
plate, and the cathode and center of the capacitive divider are 
grounded. I'd appreciate any help in putting a name to this circuit (and 
a reference to a design description would be even better).

Thanks in advance,

73,

Charlie K1LDZ
