Here''s mine made of galvanized sheet steel pop-riveted and soldered together. Finally stopped leaking after sloshing it with proper aviation tank sealer. That means it could have been made of aluminum, eh?!!

Made in 1975. 9 Imp. gallons.

What strikes me is the coning angle of the rotor. Don't know if it is an illusion or not. Seems excessively high. Did he have too much blade pitch and slowed the RRPM and did not have sufficient centripetal force?

If you look at the rotorhead block, you're seeing about the same area on the side as on the front. So I interpret that as viewing the rotor from approx. 45 degree angle. Scale the rotor horizontally by ~1.4 (sq. root of 2) and the coning appears to be much less than the image would suggest. Or I could be completely wrong, but that's my guess.
