The propeller and engine parts are grouped on Sprues A and B.
The supercharged Merlin engine and associated parts are molded on black runners as usual, along with the Hamilton Standard propeller, the fuel tank, and the "Browning M2" 12.7mm machine guns. There are also tires, pipes and the engine block in which you can see the moving pistons.

The Sprue C has the cockpit parts, the body frame, and landing gears.
The instrument panel, the equipment on both sides and body structure parts are molded on this silver sprue. The angles are perfectly determined. From the exhaust pipes to the radiator, wheels and landing gear, everything shows the details of the research done on the actual aircraft. The control stick is installed on the surface of the main wing and comes up from the cockpit floor when the main wing is set on the fuselage, just like the actual craft.

The sprue D is really worth seeing and building!
First, please pay attention to the very solid and sturdy main girder of the P51D. The highlight of SWS kit is brilliantly shown here. In addition, the engine frames, mounting area, frame structure, and the installation method are accurately represented too. Combined with the reproduction of the cooling pipes, the Mustang will be radiant. It is too bad that it can't be seen. Still, some say that unwillingly, it will continue to live on beautifully in your memory.

Sprue E has both outer body panels, auxiliary combat tanks, and air filter panels.  Sprue F has the dorsal fin type vertical tail, rear fuselage, and the leading edge of the main wings.  The tail-warning radar antennas can be seen in the middle left.  These parts are so small that you have to be careful when you work with them.

Sprue G has the gun panels, main gear covers, and cowlings. The key point of building the Mustang is in how to reproduce this complicated curved surface of the fuselage.  The streamed curved surface leads to the propeller spinner and shows the excellent beauty of its mold.  The horizontal stabilizer and the fillets of the main wings can be set up smoothly.

The main wing part which is finely sculpted in an accurate square shape is on sprue H, and is molded as a single part.  The  5-degree dihedral angle of the Mustang's main wing can be accurately reproduced by anyone, this way.  It also faithfully shows the features of the laminar airfoil.  You can thoroughly feel the brilliance of the best fighter in the world. It is also precisely represented that only the front gun panels open upwards and the rear panels and the rectangular shaped ammunition bay panels can be detached. 

Sprue I has both sides of the nose and the center of the fuselage.  Then sprue J contains the upper sides of the body and the base of the canopy.  You have to pay attention closely to cut these parts off from the sprue.  Be extremely careful!  Please use good pliers and cut the parts with a little margin from the edge, not too close to the parts.  Then smooth the surface with knife and sanding paper.

There are three canopy types on sprues K and M, and the various pipes are molded in sprue L.  The rear canopy part has a seam line in the middle of the mold due to reproduction of the expansion of the bubble type.  Remove the seam line with fine sanding paper and smooth the surface with compound.  Then you can make a beautiful canopy.
