I used the information on the website mentioned earlier as the basis of my changes, and from finding a few pictures on the Internet to modify my original tug. As mentioned earlier, I also used a bit of artistic licence rather than make it one hundred percent the same as the original.
On the website that person I believe cut away the stern of his tug, I didnt bother doing that as I didnt think it necessary as it was never going to be a working back end and I didnt fancy doing that for a first attempt.
With regard the dusty effect, the deck weathering was a good thing in itself. I used a combination of several colours - various shades of brown, black, red and green and mixed them in various combinations and thicknesses on bits of card and then gradually blending in over about a week, sometimes using the full extent of a brushes bristles, other times flicking the bristles.
About two thirds of the way through I sprinkled real dust over the deck and then weathered a bit more. After the final few blobs of painting, I blew dust over again in parts and left it all to dry.
I must confess for a first attempt at modifying a boat to such an extent and experimenting with weathering, I have been quite pleased - probably beginners luck
