I have recently bought an un-finished 2B and the original donor car wiring loom has some issues. I have the PDF of the Vicki Green loom and I think I'm capable of building a loom myself.
Before I embark on this journey, could any of you tell me if there is a company selling looms for this application?
Also if anyone has a Vicki Green or premier loom gathering dust I'd be very interested to buy one.

Think you have answered your own question - Premier Wiring and Vicky Green.

I would reccomend Alan at Premier wiring - they actually work out cheaper than buying all the components and doing it yourself.
