RAF / USAF DF Tower.

Hi, thought I would post on here as I have just purchased one of these to fully restore. Reading topics and searching the web it seems there are just 2 of these early timber type DF huts/towers known to exist.

The plan is to restore what I have and then recreate the missing top tower part. and fully fit it out inside.
So I plan a trip to the Windyhead Hill example to take more pics and detailed measurements.

Does anyone know if that example (Windyhead Hill) is still standing as the photos were taken back in 2006.

Would I be correct in thinking this type is the following:
VHF/DF 11034/42
D/F Tower, Timber, 505/40.

Any information what so ever on these would be gratefully received so I can restore it correctly.

My ex Harrinton or Grafton Underwood example:
