This is a conversion of the Fujimi Seaking kit using the Model Alliance Mk 50 conversion set and Great White Shark special anniversary decals from the same manufacturer.

The conversion set provides the air intake filter, main door steps and a few of the bumps and aerials.  The hook slung underneath the helicopter and the wiring attached to the right hand side of the fuselage is scratch made.
The decal sheet is a work of art in particular the Great White Sharks. The union flags come in several pieces and went on with only minor touching up afterwards.

Anyone contemplating this particular aircraft please note the position of the window on the left hand side of the fuselage. It should be in the position further to the rear than my version, something I did not spot until way
 too late, I simply put the clear piece into the opening that was already there without first checking the references. Thankfully there was still enough room for the decals to fit around the window so I was able to leave it as it was.
