I did order some shells from Atlas to model BLMR engines, GP35 Phase 1a and Phase 1b and I can't see any difference beside that one must be an old Kato shell and the other a new Atlas one (color of the plastic) same doors, same fans, same exhaust, everything looks the same to me... what should be different ? thank you...
edit: phase 1a and phase 1b and not phase 2 ;D
