opinions on these RAF nose cones anyone?

[Guppy35]

Canadian built Hurricanes did use Hamilton Standard props.

Canadian hurri seems likely if we're being fanciful then.

Yes, and the other tools needed to work on the engine.  Rolls-Royce used, IIRC, metric tools and Packard used imperial tools, or vice-a-versa.

Britain wasn't metric back then. They used Whitworth tools.

*prepare for photo intense post*

So I went for another visit and took some snaps of everything I could find on the spinners.

serial number on one of the cones, hard to read but I think it's 10689





assembly number I think



88888 P3 whatever that means


and the same sort of thing on the other



a different random number on each untitled as far as I know



698 or 869, your guess as to which




That's all I could find, one of them didn't have a serial number.

No idea if any of this helps identify the aircraft they were used on or not.

 Most Hurries built in canada were built w/o nose cones...but not all. Sea Hurries all, initially, had nose cones.
 Anything else from those more knowledgable?
