Hello Michael,
I once built a model of a UC in 1/35 scale for a model exibition.
I got the idea from lots of pictures with Canadian tanks and truck covered in chalk writing, mostly from young dutch girls hwo where very happy indeed to see so many young men ! Very typical of the period was that even though a lot a girls knew how to speak English, the writing skills where less developed. On the left in the picture you see "we luv joe", phonetic Dutch for "we love you".... I got this from from an actual photograph of a Sherman.
Could this be an idea for you ?
Martin.
