What airfield?

Two questions arise.

1. What airfield?

2. What Stop Butt? Unusual in that the guns are being fired into a narrow 'doorway' rather than the usual full butt.

Any ideas?

I can't get your link to open, but does it look like this? (I don't know this location either).

I am only commentingmon Oss"s pictue amd wondering if the bit on the left is made of planks and is positioned just in front of the butt. The rounders may be targets in which case the shot is not of the total width of the butt. Does this make sense?

Don't know why, but the Flight Global webpages put up some selections as 'blanks'; it wont open for me either and for anyone to make an assessment you really need to see it.

The image shows the port wing of a Spitfire firing (two?) guns into an aperture in a 'Stop Butt'. There is a high brick-built wall with a shooting-in aperture more like a doorway than a 'butt'; there is a prominent roof overhang above the aperture. It is attributed in the caption to 'a Scottish airfield'

In your image (Post # 2) I would say was taken at an Air Gunnery School (AGS) such as Stormy Down. The turret azimuth 'stops' would have been pre locked to ensure bullets went only into the sand-filled butt. Looks like a Boulton-Paul Type D turret with two .5 inch (fifty caliber) guns so late=war.

kebecker, no the side walls are brick. The 'roundel' targets are for a harmonisation (boresighting) check I would think for four gun turrets.

I managed to open the link using firefox.

Page says "1940" and show a spitfire test firing its port guns.

I too opened it in Firefox and down loaded the PDF. I have been trying to decipher the squadron code as a clue. The aircraft letter Q is easily discernable, but the 2 squadron letters are more difficult. It looked like P something. Possibly PR or PB, but there weren't any spitfire squadron with those letters.

It opened today after some fiddling so I took a 'snip'

The caption says 'A Spitfire of a Scottish squadron' implying that it is somewhere in Scotland but of course it could be elsewhere. Flight dated 28 March 1940.
