Ansons didn't usually have MGs. P38 Lightning had four .50cal in the nose.

Some Avro Anson were equipped with a single forward firing machine gun and some with a turret with just one MG. So certainly not Anson as this is marked gun #3. Lancaster rear turret? Lockheed Ventura?
What about the F86 Sabre?

Certainly not Anson or Bolingbroke, neither of which had 3+ MG
F86 might be a possibility

That is really great homework friend.
I suggest contacting an aviation museum curator as your next step. And maybe contact that last American aviation company that uses the last airworthy Sabre jet a target towing aircraft in North America.
there are actually quite a few flying sabres in private hands. look up agentjayz on youtube
