Unknown installation, can anyone identify?

But forty years ago there was a lot there!

No water tower on the plans for Hunsdon, but there is marked a 'Sleeve Streamer Mast. as #245 on the plan. This was not exactly situated where the plan says it should be, but is in the immediate area. Can someone post an image of a 'Sleeve Streamer Mast' and its base for me to compare?. Ian might well have been right after all!

That explains things a bit!

Isn't a sleeve streamer a windsock, if so that base seems too large.
Could there have been a EWS in the area? Would all water supplies be necessarily marked on site plans? St Athan has a Braithwaite that dosen't appear on plans, surely every station would need some kind of its own water storage/reservoir (thinking about your point of no water tower on plans).

From the photos it's unlikely that it's the base of a Braithwaite tower. There are usually sturdy I-section girders with cross-braces.

It looks more like the base of some sort of antenna mast from the triangular mountings.

All the best,

I agree with Paul. Look at the close-up image of one of the metal supports. The glove gives scale making the sides of the triangle about 130 mm; even four would be inadequate to support the legs of a decent capacity water tower.

Agreed.
I assume then that there is about 10" between the mounts centres, seems reasonable for some kind of antenna tower as PB suggests.

Just to clarify
The base is 11 foot square, the mounts are set in from each corner by about 18 inches. The mounts themselves are exactly eight feet apart.

As I've said on many occasions there is nothing more exciting than a lump of concrete with a metal object embedded into it .

My sentiments entirely Graham:)

But it is frustrating to find these things and not know what they were. I literally fell over the damn thing having probably walked over that spot countless times in the past. Its seems that this year the undergrowth has been burned back by the frosts, exposing both that, and the concrete ring gunpit I posted on the Hunsdon thread.

Did you find any cable conduit in the concrete base Denis.

I am going back there tomorrow with a spade to clear the moss from the base for a better photo Chris.
