Geograph - photograph every grid square

RAF Benson

The main entrance to the airfield, with the usual plane on a plinth in the background.
Are these all real old aircraft or models specially made?

Update from Mick Lobb : Gate guardian aircraft are often the real deal but in the case of the rarer types are fibre glass mock ups - often to a reduced
scale. This is a replica Spitfire PR IX celebrating the role of
Benson in WW II as an aerial photo reconnaisance (PR) base.
