The very first 'Super Puma' was one of the original bulbous nosed 330 prototypes with Makila engines, single wheel undercarriage and a one metre plug in the rear fuselage. The production model switched the plug to the front.
The Mk 2 reintroduced the rear plug so now the 332 L2 and the 225 have both plugs.
The plugs are easy; the problem is with the windows and the undercarriage plus supports.
Or you could start with this....
