Brian Smith sent along this very sharp looking picture CN 4730, a GP38-2 built in 1973. Brian took the photo last Saturday at the yard in Huntsville, Ontario.
Not sure how this could be modeled, but maybe paint the long hood white, then a layer of chipping fluid, and paint over that with black acrylic. Then start removing most of the black until the effect in the photo is achieved. As for the primer coloured diagonal stripes...maybe paint stripes from a decal set and apply them. That's two maybes. Best of luck to anyone that tries them.
