Thanks Bushranger. TBM, for historical accuracy the Navy Hueys were all B models, no C. The only C's produced went to the US Army, and 6 to Spain. The C had a different tail boom and rotor system than the B. The Navy did have one odd child though, an aircraft with a C type forward fuselage (bigger fuel tank than the B) and a B model tail boom and rotor system. The production run lists that particular aircraft as a B, and I don't know how even official RAAF and Navy sources refer to C models. One RAAF source states the Navy as having 3XB and 4XC.
