Looking more like a science fiction robot, this shot of a Bf 109G-10 firewall provides a good idea of the different shaped bulges on the Port and Starboard sides.

Note the light blue attachments to the side of the upper firewall. These are the internal covers for the fuselage fairings behind the cowl bulges.

See how the Starboard profile (on the left side of this photo) is much flatter than the Port side, which is both wider and curved outward. This complex curve curve extends further out as it travels forward on the engine cowl.

The Port side cowl exhibits all the features expected in a Type 090 or Type 100 cowling - namely the shorter, pressed insert and the forward vertical panel line.

The curve of the bulge is also clearly illustrated at the back edge of the cowl.

The continuation of the bulge to a position somewhere forward of the supercharger intake hole (then tapering off until the vertical panel line) can also be made out with the help of the reflections on the shiny metal and the backward angle of the hole itself.

Note that the cowl halves are slightly splayed.

Starboard cowl looks closest to a Type 100 - the access hatch to the cold weather starter is in the higher position. On a Type 100 cowl the old access hatch should be present immediately below the new. It was usually welded shut. However, there is no evidence of the lower access hatch on this example.

The Starboard side cowl is clearly not nearly as curved or complex as the Port side. It is, in fact, quite a simple fairing with an almost flat, vertical appearance at the back of the cowl.

In summary, then, the sides are asymmetrical.

The Port cowl viewed from this angle demonstrates the continuation of the bulge to near the top of the cowl, behind the port machine-gun trough. This bulge covered the larger curved engine mount, itself required to clear the larger supercharger of the DB605 AS and D series engines.

Also clear in this view is the deep oil cooler and the oval shaped "bump"at the corner of the lower cowl. Note the distinct "step" at the front and rear of the oil cooler. It is slightly odd that the oil filler cap on the cowl ring in the lower position is missing altogether. It should be welded shut, just above the forwardmost scoop.

A good shot of the  fuselage fairing typical of Type 100 cowlings. This illustrates how the fairing is simply riveted to the fuselage side. Note the small, triangular fairing similarly attached under the side of the windscreen.

Once again, reflections highlight the complex angles of the Port side cowling, and the extreme nature of the bulge.

Straight side view of the Starboard cowling.

Note the big kink in the upper leading edge of the Port Wingroot Panel, and the corresponding kink in the Port Side Cowling immediately under the hole for the supercharger intake.

There is no kink on the Starboard side.

It is clear that the cowl intrudes significantly over the Port Side Wingroot Panel (left side of photo). Note the difference between the Port and Starboard sides when viewed at almost the same angle.

The Wingroot panel fits right here. The front of the panel goes right under the supercharger, with the panel extending back to cover the gap between the port wing and fuselage side.

Note the temporary cover on the supercharger intake.

The wing has not been installed.

And here is that big supercharger. A portion of the curved upper engine mount may also be seen in the top of the picture.
