OK chaps, your N scale modeler has been hard at it with very little result, as a contractor he'd have been dismissed weeks ago but there could be a solution to the problem of texture on walls and roofs of buildings.

from an out of state tin roof salesman, shingle walls and roofs have been deemed
the work of the devil. And it's a big relief all round.
