Hello CharbensYY, I saw these over on 'Moyboyz' and have made a comment about the models going into the wrong boxes. You say they were out of their boxes before your involment with them, so that's OK, it was not your fault.
To get them back in their correct boxes is going to be a bit hit and miss, because to the average collector (not saying you are average...

), they do seem to be the same models. My advice here is to put the cleanest and better condition models in what appear to be the cleanest and better condition boxes, the Army models have their own distinctive box, so that should not cause you any problems. I mention over on 'Moyboyz' that the last issue models will have been in the 'Clear-View' boxes, I do not collect this range in general, only have the Rolls-Royce and Vauxhall models.
The Rolls-Royce in my 'Clear-View' box has a stepped steering wheel and the road wheels painted on both sides, where as issues before this had a smooth steering wheel and only the outside of the road wheels painted!!
