I'm looking for the reference to the Huff-Puff stabilisation scheme, and in particular the improved Mark 2 modified version that, seem to recall, employed a counter rather than a simple flip-flop. It almost certainly appeared in Radio Communication in the 1970s, and from what I remember of talk in my local radio club in those days, was probably around 1973 - 74. Have a feeling I'm in the process of 're-inventing' it for a high stability GPS locked source for low data rate signalling, and don't want to claim the credit for an idea that appeared over a quarter of a centuary ago! With a PIC instead of all the control logic, it should certainly be a lot easier and simpler than the original concept!
