I'm not sure if you're just looking for one off members in here but,
i'd keep an eye out on ebay.co.uk mate.
i got mine from there a while ago, really cheap, with all side pockets etc.
ebay.co.uk - Militaria
Some really decent stuff pops up in there now and then.
Usual warnings about buying things off ebay apply though.. be careful
Cheers
