Hi Kimmo,
And sorry for the bad news.
I think this CMP, as rendered by the Poles (in both cab 12 and 13 versions, the former in fact Ford and the latter still not 100% Chev) and in this particular configuration (both sharing the same body 4E1
) exists only in the fantasies of the IBG designers, a stable which became famous with their sofstskin kits bad research, the scale apart.
Mirror Models CMP kits are much better, in any respect.
BTW, if this will make you a little more happy. The IBG 1/72 CMP kits are even worse.
HTH
Cheers!
