Structure within Anti-Aircraft Position

Folks,

Here are some pictures of an Anti-Aircraft Gun Position near Larne.

I am particularly interested in the last 2 photographs - This is a reinforced concrete Pillar approx 6 feet tall with a hollow centre. You can see metal bolts on either end.
There were 4 Gun Pits however this appears to have been in one of them.

There is a Radar Platform in the next field and the red bricked building between the Guns and Radar Platform has 2 large concrete plinths which look as if they have been used to hold 2 Electricity Generators the same as i have seen in Decoy sites.

Does anyone know what this Concrete pillar would have been used in connection with??

I think that you forgot to post pics of the pillar Andy.

Anyway, it was probably to mount a Kine Theodolite for viewing shell bursts and used to check accuracy of the Predictor Unit.

That Larne HAA site was built 1943 and although there is a radar ramp in the adjacent field it may have been added later.

Here's a pic courtesy of IWM:

Hi,
I should have explained that the pillar has been toppled and is shown on it's side in the last 2 photographs.

That certainly looks like the answer.

Much appreciated.

Andy

I thought they might be of the pillar but couldn't see any fixing studs.

EDIT

A nice photo/description of HAA work here:
