These photos of a MBA Mk. 2 ejection seat are from European correspondant Mark Verbeek. The Mk. 2 shown here is on display at the Militaire Luchtvaart Museum at Soesterberg AB. It is believed to be Mk. 2FKR from the Fokker S-14 'Machtrainer'.
The early style Time Release Unit (TRU) is clear as is the slightly later version double-loop face curtain handle. The seat bucket has the classic early MBA upward front sections to contain the thighs. The cloth parachute container is the early rectangular style.
