A little cosmetic cleanup of the 737s and the addition of the Classics, which i've updated a bit in order to achieve a homogeneous appearance with all other models.
Originals (737-100, 737-200):
Classics (737-300, 737-400, 737-500):
Next Generations (737-600, 737-700, 737-800, 737-900, 737-900ER):
MAXs (737-MAX-7, 737-MAX-8, 737-MAX-200, 737-MAX-9):
Boeing recently announced a finalized design on the MAX-10 with a further fuselage stretch of 66inches (rougly 1,7m) but I'll wait for more detailed informations before adding it to the MAX sheet.
