I like the U-Boat idea, but Andy has said it will never happen because (a) in 1/30 scale a U-Boat would be huge and a merchant ship or Destroyer Escort to oppose it would be like 20+ feet long and (2) there isn't enough interest in the Kriegsmarine among Toy Soldier collectors to make it worthwhile. However, could you imagine if Andy made not only the Warbirds, but the buildings, vehicles, pilots and ground crew in Today's superior sculpting and painting? If you think my old school RAF diorama is fun, I can't even tell you how much better the new stuff would look. All I can say is I have the prototype of an Austin Tilly RAF service vehicle done in todays sculpting and painting, and it is worlds better than the earlier Ambulances and Fuel Bowser.
