I love your C1-B type cargo ship model, keep up the great work Alex and keep them awesome ships coming.
Just curious though, do you have any plans to maybe make a C1-A and C1-M models to complete the C1 set of cargos, and maybe even expand on your C2 type cargo by making C2-S-AJ1, C2-S-AJ3 and C2-S-E1 models as they were the four most numerous C2 variations built along with the C2-S-B1 which you already have?
