Vulcan B Mk 2 Landing Gear Hawker Siddeley Drawings

I visited a display by the Vulcan To The Sky Trust today. I was interested to see many large display boards from Hawker Siddeley Aviation, three of which are of the Landing Gear.

The main undercarriage was certainly made by Dowty, not sure about the nose undercarriage?

The main undercarriage I believe was tested on the drop test rig at Arle Court which several people have commented upon.
