Now that's interesting.

The No6 Mk.I projector is listed as a former naval 20 barrelled projector. The only ones that come to mind are 2- and 5-inch versions.

AA Command, page 395 mentions a 20 barrelled projector, the U20P, also known as the No 6 that was deployed in batteries of six weapons.

You can see why the Luftwaffe were shy of flying near UP batteries. 120 rockets hurtling up towards you in a salvo.
To make matters worse you could see the launch flash while flying, and then you saw each rocket flare as it screamed towards you. Flak was much easier to deal with as you only realised it was there after you'd been shot at and the shell had exploded.
 
You wouldn't want to live near one of those batteries though. What goes up must come down. There must have been a blanket of falling shrapnel.

Correct, like you'd get from a salvo from a gun battery (albeit less volume in one place, but the gun batery would fire several salvo's against a track).
But technically all the Civilians would have been warned of the approaching Germans and be under cover. Equally, it's at night, how many are going to be out in the blackout?
Beaning the local Blackmarket dealer/burglar over the skull with a lump of 3-inch UP might well be seen as a positive for the authorities!
You also get the civilian protective helmet which was mass produced very cheaply, and on sale to the public for no real cost (~£15 in today's money).

I recall my mother saying that when she came out of the shelter after a raid you could hear the shrapnel hissing in the wet grass. There was also damage done to the house roof apparently.

The helmet in use.

Does that helmet qualify as uniform?

A sad anniversary.

 
An idea has occurred.

Why were 9 barrelled projectors only used in some formations, and not others? I always thought slow production was the issue. But....

All the ZAA batteries (and GS Home Guard) were suffering from manning shortages to some extent. With some area's worse than others. It takes a lot less manpower to crew a 9 barrelled projector than the single or twin ones, and yet has the same throw weight. So, I'm going to take a guess that the 9 barrelled projectors were priority supplied to those with manpower shortages.

The main cause of manpower shortages seems to be linked to area's with a high amount of shift work.

So far documents have suggested that Slough and Southampton ZAA batteries are good places to look. Although the Southampton one was fixed by disbanding one battery and combining it with another. And the Slough one is from the local command suggesting the 9 barrelled projector might be a fix if they can have some, please!

This file has another 400 pages in it, so lets see what turns up.

Edit:
Chelmsford and Colchester also appear to be in the same boat as Slough.

Is there any correlation between LAA and HAA deployments and projector type?
 
Is there a predominance of 9 barrel projectors in rural/coastal areas and single/twins in/near urban areas? If so, it could be a practice to minimise collateral damage. Equally, to come back to manpower considerations, less transport would be needed to get the crews to more remote areas.
