Do you have a close up pic of this?
I am working on a 3d series of M-1's (m-1, m-1a1 and m-1a2), and that is a cool thing to note for the texturing. Also, is it just on the road wheels or also the return roller and drive sprocket?
How that would get painted in 1/35th scale, I know not but I am sure someone will find a way.
3d modelling is an option
a true mental excercise in frusrtation
