Star Trek Wrath of Khan uniform extras

Has anyone in the UK come across a supplier for the chain which is part of the TWOK jacket/uniform? Additionally has anyone used the xscape pattern to produce one of these. Finally is there a decent (ie reliable, not too expensive!) supplier for the fabrics needed?

The chain is not being produced anymore. What is out there is out there... As for the fabrics, you have choices, but Wool Elastique (98% wool, 2% elastic) is best, and then you need to find the color or dye it. This material is NOT cheap -- about $80/yard (USD). The patterns from Xscapes are good, but you will need to modify (tailor) a lot to fit your individual frame...
