I remember reading about a model boating society that, instead of wargaming, would create scale models of famous warships and fight them - the hulls would be thin wood, and the turrets had motorised mounts and compressed air guns capable of firing a metal pellet through the wooden hulls. The ships would have less internal bulkheads (to account for the damage explosive shells would cause) but would otherwise try to be as true to life as was possible given the limits of technology (I don't think anyone was building gyro-stabilised gun platforms, for example, as it was too hard to minituarize).
There was even a proposal to build larger scale ships that used small-calibre handgun ammunition and sheetmetal hulls, but it was shot down (if you'll forgive my pun) for being wildly unsafe and probably illegal (as I understand civilians are generally discouraged from owning remote-controllable firing mechanisms).
