What a coincidence!! I got a desert one of these today from a source in the UK. It's my second one so I'm putting it up on eBay. I have desert trousers too, so I'm sure there are temperate trousers to go along with your shirt.
I also have pics of a CD6, with what appears to be minor differences from CD2.
Anybody know the story behind this one? I'm guessing it came after PECOC trials?
