That would have been my second guess. I spent a good while looking at tube implementations of both of these and I ended up deciding on Colpitts because it is referenced more often in relation to UHF design.
Is the slice of tuning mechanism that runs from the wiper to the chassis connection the bit that forms the second inductor in a Hartley?
