Look at the head and shoulders, this is the S or Ex-S Gundam, not the RX-78-2.
I would agree with the fact that it is probably the Ex-S Gundam 'cause the antenna in the lower part of his head is an attribute of this model. But where a pair of higher antennas? Moreover, among the debris not seen a huge amount of rig, that usually has this model. The shoulders are not like Ex-S's though^^ But if you confident this is Ex-S then I'll fix the tags^^ P.S. & what you thinks about post #1845951 ? Is this truely Nu Gundame
Have to agree with DanteFromHell here. The chest is just all wrong for the MSA-0011 line. The shoulders are a pretty generic design feature of later series. S and Ex-S had very pronounced shoulders, with these being modest in comparison.
