I did try an old Tiger SLU in there, but the sound kept cutting out. A magnifying glass revealed a few dodgy solder joints on the pcb (it looks like it was repaired at some point in its life as some joints are shiny, others are dull), which is probably what is causing the problem, but I can't be bothered to pursue a solution to that.
The two tone camo was very difficult to match. The real thing is green/sand and grey/green but the shading looks different depending on whether it is indoors or outdoors, and any pics taken of it also get affected by light so no two pics ever look the same colour. At the end of the day, I am taking the view that prior to capture it could well have looked like this.

I'll add a few stone chips and scratches when I do the decals.
