Knocked this up yesterday for tonight's 1938 "A Very" British Civil War game at the Reading club.
I wanted a simple cargo barge, suitable for 25/28mm figures. This has a simple balsa hull construction with thin card glued and "riveted" in place. The wheel house is just simply made from 4 pieces of balsa with the windows marked in by being pressed with a pencil.
I have sacrificed detail for playability and have made sure that penny-based figures can walk around the deck or stand in the hold without falling off!
I'll post some pics of the barge in action after the game. Can't say too much - the players might be reading this!!
