This is the Wessex HAR.2 from Mark 1 Models in 1/144 scale. It's a nice kit for the scale with recessed panel lines and pretty good detail overall. I added a little bit of cockpit detail including seat harnesses and instrument gauges, and also built the winch above the main door.
Because of the short-run nature of the kit some of the panel lines were quite soft, so most of the lines were re-scribed to make them sharper.
The main concession to accuracy was the rotor head. I needed to make the rotors removable for storage, hence the utilitarian approach. It looks pretty crude on the enlarged pics, although at actual size it's not too noticeable.
Yellow's not the easiest colour to apply so I primed the model with pink, then airbrushed thin layers of Tamiya X-8 Lemon Yellow until the right shade was achieved. Mark 1's decals were awesome, with lots of stencil detail. The various aerials were added from stretched sprue.
