MK26b (seats)
Maxred; the Mk 26b does have two seats, but it is not a replica of the original Spitfire Trainer (that had two 'bubble' hoods on separate cockpits) with the second seat higher than the front one so the instructor had some forward vision.Nicks aircraft does not use the original Vickers mod as in service with the Irish Air Corps,but has a hood similar to the front seat,and set in line.
The MK26b uses the space behind the front cockpit as a 'jump seat' for a passenger.
