My "A" model has 5 sprue sections counting the clear but the rotor blade and floor ,roof sections are joined together to make one big one so maybe 6. It's molded in gray. The others are molded in OD. The MH-60K kit # 2153 is the best deal if you have to buy another one. It has some great new M-60's in addition to the crappy ones, mini-guns, .50 cal, ammo bins, internal fuel cells, upswept ESS wings, current HIRSS exhaust, extra horizontal stabilizer, refueling prob, external fuel cells, full complement of seats, covers for the ESS mounts, Flir pod, nose radar(two kinds). The works to make any variant you want to. They are usually the same price too.
