Try the ASPT Fox Lines (or is that what you meant by APTC?) they definatly have them - for about Â£30! these are the ones without the flyaway concorde wings! they seem to have updated their website; http://www.army.mod.uk/aptc/pri_shop/index.htm
but they have got them there when I did my course a couple of the lads got them, they do come up on ebay now and then, keep an eye out.
