It does make me wonder why companies don't sell seperate crew figures as often. Great Escape Games have many, but others not so much. It'd be nice if Rubicon were to throw together some more sets - as they have the STL files there, they just need reposing. Or rather just sell the already seperate crew sprues which come with their kits by themselves...
Warlord has a nice set of figures for a Pak 40 which would be suitable for these late war vehicles. I may sneak in one for my own Ardelt Waffentrager. Though to be honest its more sitting figures which would be useful - which isn't that common a pose. Ive considered using some of Offensive Miniatures tank riders actually. Though for however many companies do seperate crews, finding the right poses for a particular model, then having them all with the same proportions seems like more hassle than it should be.
But folk like their tanks more than they do working on the crews it seems. Or at least a vehicle's simpler to model than alternative crew figures. Most modellers are probably fine with what comes in the box, and wouldn't even consider trying to source say a Soviet crew for an American tank. And those that do want that sort of thing either settle, or convert what's available.
