we have been asked for them in 28mm as we do them in 20mm and have a range of 28mm models.
it would be a big model indeed and i would like to add it to the list along with the cougar 6x6 and 4x4 for the yanks, but sadly time is against me at present, but i never say never anymore.
it is on our 20+ club list of wanted 28mm vehicles.
