Sorry to disapoint, but the sampan is done. No other parts, and I am satisfied with the paint. From the pics I have seen, that is as good as it gets with me doing the painting.

I suspect these sell much better with the Vietnam guys that game it in 28mm (I think Bolt Action is bringing out a game as well).
The sampan was a last second idea as it was pretty darn cheap. The push for me was the fact the canopy-thing comes out and it looks fine as a small boat like you suggest (and it was only ~$7 IIRCC).
