I believe this is the gun.

I would agree, it's for the British QF 3.7" AA Gun, an interesting and rather unappreciated weapon. In it's mobile form it was very similar in appearance to the famous German 8.8cm Flak, but actually of larger calibre (94mm) and in performance generally superior. It wasn't used in an anti-tank role as often as the 88, but was formidable when it was. It's only drawback was that it was much heavier than the 88 and therefore somewhat less easy to get into action.
