Maybe it happened more than we know.

Supermarine didn’t start to fit mirrors until September 1940, but there are stories of pilots going to the local car dealers, and getting their own (your Triumph items, perhaps?)
In December 1940, a leaflet was issued, telling units how to fit their own, and it called for “26AJ/24855 Mirror, Desmo Type 44 (2 lug attachment.)”
An “improved” mirror was introduced in December 1942 (sorry, don’t know the type) on all Marks, except P.R.

Not Spitfires but Hurricanes at Duxford, according to this chap.
“They had the Messerschmitt and they would try to get behind our boys where they couldn’t see them and hit them up the tail,” he said. “One day my section leader said go and get some car rear-view mirrors. Flight Lieut Pearce has designed some brackets so we can fit them in our planes. Try and get 50 so there is a mirror for everyone. I got a WRAF to drive me into Cambridge and I went round the car dealers. I told them to them out of the second-hand cars. I got the 50 mirrors and they fitted those into the Hurricanes so they could see what was going on behind them, and that modification saved quite a few of our pilots.”

Like his quote about Bader.

I would not rule out target drones, they flew from Stiffkey to Weybourne for gunnery practice.

9th June 1940. Heinkel He 111H-4 (8747) from StabII/KG4
Shot down by Flt Lt Duke-Woolley in a Blenheim no 23 sqd. Forced to ditch just off shore at the Hood Cley next to sea at 12.50 am. Crew taken prisoner. This was the first enemy aircraft to be shot down by a night fighter over Britain and the crew were the first POWs to be taken in Norfolk.
The wreck remained offshore until1969 when it was blown up on the orders of Trinity House as it was considered a hazard to navigation.

3rd May 1941 Junkers Ju88A-5 ditched off shore at sparrow gap Weybourne at 3.30 AM.

30th July 1942. Dornier Do217E-4 Crashed on Salthouse marshes at 2.00 am aircraft destroyed.

Guess the North sea had a lot of planes crash in it, in ww2.

The guidelines, of course, were way out of touch. “‘Nigger’ is a good case in point,” Clarkson went on. “When I was growing up it was no more shocking than ‘cauliflower’.

Clarkson born 1960.

It was in the US army. Just one case of racial abuse is recorded in the second Air Division Memorial Library archives: a private in 491BG is charged with using the “N” word to the soldiers of company B, 827th Engineer (Aviation) Battalion at Metfield on the night of 17th June 1944. The man was court-martialled and fined $40 with three months hard labour, but the confinement was suspended.

2 (i) A borough of rateable value £1,600,000 levies an annual rate of 22s 3d in the £.
What is the annual revenue produced? = £3.522,000

I calculated that they received 22s 3d for every pound they had,
22s =5280d + 3d 5283d x 1600000 =35200000 / 240 = £3,522.000
But have no idea, if that’s the correct way to do it.

(iii) A mans salary after being increased by 20% was £810 per annum. What was the amount of the increase?

You are right on that one Edgar, I did not read the word after so calculated the 20% on the £810.:o

Guess thats why the questions are written in that way, to catch the pupils who have not been listening to their lessons before hand.
