At least for crew sticking their heads out of hatches, wouldn't US World War 2 tankers work?
Tamiya included a couple of really swell 1973 era guys in their Tiran 5 kit.
Their’s and Academy’s M-51 Sherman kits also come with some decent crew figures. It’s a shame that none of the new Dragon IDF kits come with appropriate figures, or that they do not release some sets.
But yes, to make to 67 or 73 War figures, you’ll need to do some conversions. Hornet heads help.
