I just had one of these installed.

I thought they were called air brick covers/ventilator, so why is this thing called a Hit & Miss Ventilator ?

Perhaps because they have a vague resemblance to a wooden structure
such as this:

It's probably one of those terms that is better just to accept rather
than rationalise.

"hit and miss" signifies the way they can be adjusted by sliding across
the moveable screen.

OED has a definition:

Chambers's Techn. Dict. 417/2 Hit-and-miss ventilator, a ventilating
device consisting of a slotted plate over which may be moved another
slotted plate, so that the openings for access of air may be more or
less restricted as required.

spot on .......also comes from drainage trap top piece cast iron covers
which ventilate and at the same time stop debris dropping into the
trap.......

My theory, that i will try to explain. (But will fail, because my
English is not good, i am a Kraut)
Look at this:
http://rts.vents.co.uk/blog/product-...ss-ventilator/

It is made of 2 identical sheets of metal with holes in it.
The sheets can be moved parallel.
If a hole in sheet 1 meets a hole in sheet 2: Hit! -Airflow
If a hole in sheet 1 meets a 'non hole area' in sheet 2: Miss! - No Airflow

Hope, you see what i am trying to say.

I'm hoping we'll have proper windows by then not plasterboard with a hole cut in it for ventaliation !

These grey areas on the wall will be windows hopfully by April 2018.

To grab your attention to get you to buy it, stupid.

Typical wog.

Because of the lining up or non lining up of the holes in the static and
moving parts.

Didn't grab my attention until I saw the empty packet on the floor and I put it in the bin, bit late for me to buy it then as it had already been installed.
