Hi Scott and Brian. Thanks for your nice comments. Regarding parallelity and the roof line ..... the warf and house are not parallel to the base, and unfortunately the roof line is the only visible result from this angle!
The base has the width constraints of my display cabinet, and has to be long enough to hold the DUKW (and will be quite compact when finished), so its not an extreme angle. If the house was parallel to the base edge, the roof line would be parallel also, but as you can see, there is an angle. The next time I take pictures, I´ll include one from above or from the side so this can be seen clearer. Cheers.
