Hi,
This may fill a gap.
They have the Boeing 737-300 in the works, also a version with winglets.
The only point, I see with regret, that they have no Repaint for typical users of this aircraft in Eastern Europe like Air Baltic, Ukraine International… Hope, they do something in the future or that repaints come frome here…
Liveries of Air Baltic and Ukraine International are not a problem. Someone will paint them.
