Decades ago when I was in my teens I was heavily into 1/72 and 1/76 wargames (i.e. World Of Tanks - 1980 style) and one of the biggest (it was 1/76 unfortunately but would have been if it was 1/72) and baddest would be the JagdTiger. Fujimi is the only one I believe that makes it at that time and even now, when you say JT what comes to my mind is the grey colour JT on their cover box art:
I know that this is not exactly Tamiya box art, but one would think that there must be some historical basis. Of course now that I am older but not necessarily wiser, I don't remember seeing anything newer than the Panther that has factory grey, not King Tigers and definitely not JT, not to mention the almost "baby powder blue" colour on the box art.
If anyone can shed any light on this colour scheme or have information on the factory fresh JT base colour that would be much appreciated. My guess right now is the standard dark yellow or oxide red if it is not painted.
P.S. Just in case I am not being clear, I am seriously considering painting a JT grey........
