Anyone into airfield lighting?

[DavePanda]

I live on a former USAF base and picked up this runway light recently, said to be from the base i live on. From what i've managed to find out so far they were made for the RAF/USAF by Thorn and used an ERH-B2T Bidirectional light. Does anyone know the chances of finding said light fitting? They're long since replaced by LED's and, it's not then end of the world as it's going to be a garden ornament but thought it might be kinda cool to get it working
