Looking at the 2 trucks, there is no visible difference to my eye.
It is the data plates, that separate the M133 kitchen sister truck to the m135
When finished as a usable pancake etc truck I hope it will look like the picture supplied. When I or the museum find any differences I will post here.
I will feel better and know more when I get them from north of Hazelton
to my place in smithers. As the scrap dealer said possession is 9 points of the law. de3nnis thanks for the replies.
