    Altering the air inlets to compress more air? or Altering the wing shape/angle to provide the same lift in less dense air? Not sure why they'd want such a high voltage to do either though
  2. Lauren Child
    thinking of low density air, maybe some kind of air speed sensor?
  3. Lauren Child
    Rightho, that's into the stratosphere then. Low air density. Maybe something to do with static buildup from convection around thunderstorms?
  4. Lauren Child
    Is it something to do with static electricity? Maybe zepelin/aerostat tethering?
  5. Lauren Child
    lightning arrestor?
  6. Lauren Child
    Which implies capacitive. Now what would you want a 1000V capacitor for?
  7. Lauren Child
    Maglev trains ? (German, 1934?)
  8. Lauren Child
    Starter for jet engine?
  9. Lauren Child
    electro-magnet for lifting?
  10. Lauren Child
    That's an interesting thought - An HT inter-vehicle stary would be more efficient and travel further, needing a smaller size of cable.

    Or, being high voltage, maybe for flourescent lights under a particularly blingtastic kubelwagen?
  12. Lauren Child
    is it for electrifying the hull of a vehicle, or a fence/barrier outside of it?

    It's a nice thing. I have to say, I wonder if there's an interesting story behind the Cromwell marking. Is this the same one that was on sale at war and peace? That one was marked "Cromwell IV". While it may not be a tank one, one chap I spoke to commented on the box being a rarity although he was passing it up as a better condition (but unboxed) sight was on another stand. As such don't give up - once you've identified what it really is I'm sure you'll find someone who'll love it.

    Good call

    Hold on, 1000V. is this the back of a CRT or similar?
  17. Lauren Child
    Welding?
  18. Lauren Child
    It's not something to do with UV night vision is it?
  19. Lauren Child
    I was actually thinking Krytron and got mixed up - either could be a good-un though
  20. Lauren Child
    Klystron tube?
  21. Lauren Child
    As far as I'm aware, Cromwell didn't use a binocular sight, though if it's the one from W&PR the box is indeed painted with "Cromwell IV". Can this be used as a range finder?
  22. Lauren Child
    Bliney that was quick!
  23. Lauren Child
    Wow, that's an odd one. The second pic looks a bit like a door with a hinge bracket running across it.

    Wikipedia's not always the most accurate, but a google around seems to confirm it - ZDP / ZDDP replaced the lead part of EP oils quite early on. https://en.m.wikipedia.org/wiki/Extreme_pressure_additive More here - https://en.m.wikipedia.org/wiki/Zinc_dithiophosphate If you pick up some of the engine oil additive, which should be the same stuff, it might help.
  25. Lauren Child
    That's because it's already in EP gear oils, so you don't have to add it, along with sulphur.
