I really don't know why you lot are having so much trouble understanding the basic operation principles involved in this as it was the primary power unit used on the Mk91 Gyro Compass as installed on the Sydney.

Pretty basic stuff actually.

Gordon, my respect for you just increased tenfold. You are actually crazier than me. :omg1:

Didn't Naval Stores used to get the Gyro Inverted Sprocket Drive Perambulator confused with the Inverted Perambulator Sprocket D Drive because there was one number difference between the NSNs??

I do believe PW that on this singular occasion to be absolutely correct.

Not sure Pete, but the boxes were the same size and even the same colour, with the handles in the same place. I suppose they got mixed up as every time we would get a spare unit, the bar code on the label was printed upside-down and the system would read the number backwards. So this would correlate with correctly printed number for the Inverted Perambulator Sprocket D Drive. We actually received the correctly ordered part but the Naval Stores System probably thought that we needed the latter unit and as we were ordering them, would requisition the Inverted Perambulator Sprocket D Drive instead of the Gyro Inverted Sprocket Drive Perambulator. Thus there would be a surplus of the Inverted Perambulator Sprocket D Drives in the stores system and they ran out of Gyro Inverted Sprocket Drive Perambulators because none were being used (according to the system).

So in hindsight, I'd say you were quite right about that.

By the way, I did see an Inverted Perambulator Sprocket D Drive in the local Surplus Shop but it was a blue one and probably wouldn't fit.

We used to have a similar problem with the Paxman D/G conglomerating fluximaters. I think they had something to do with aligning the generator speed with the amount of 'erbs being generated by the electrical thingo!!
But, boys, boys, boys ........ we are way :offtopic:
