On closer inspection of the OH-6 the skids had been put on backwards, but I was able to pries apart the 2 half's of the body by putting a small screw driver up the engine jet pipe. This has opened up the option of not only painting the inside of the cockpit but also perhaps using the Peter Pig Hue crew, and put some additional detail in the cockpit.
In the bottom picture I've put a steel ruler in the shot for people who are interested in the exact scale of the model. For people like myself who have a more relaxed attitude to the exact scale of things I've put a Peter Pig 15mm scale 8th army figure in the picture. Looks to me just slightly over scale, but not by much. Next mission is to go and find some more, 2 should do it.
