Given some width issues I think I'll try Dixon's lounging Cowboy, that means a call to Scale Creep in the morning I suppose. Thanks.
Construction wise it was pretty quick and simple - did it while watching TV last night. I cheated and used a Reader's Digest "Horse Drawn Pumper" wagon that I removed the pump from
and then constructed the back box by using some curved bass wood (meant to be a 1/12th scale chair rail I believe) to make three picture frame shapes that were glued to a gridded 3x5 note card with white glue.
Once that was done for the two sides and the back I cut the pieces out of the card and cut out the windows. The bottom and front were cut from a 1" basswood strip. The top was cut from a wood ruler to give it some shape. I then sprayed everything black, and the windows were cut from a handy blister pack. The trim took just a moment with some dulled gold paint.
