Don't know of any off hand, but Italeri do a set for the German E-Boat which could be converted. Alternatively, there are various nationalities of soldiers, and air and ground crew figures, available form Airfix, Heller, Revell and Italeri, all of which could easily be converted to what you want.
Although I work in 1/48th scale, I rarely find a figure I need, and mostly convert them from, for example, the Tamiya Panzer servicing crew, German infantry etc. A bit of carving and Milliput works wonders !
