I got mine from Burton Bike Bits, 138 Waterloo St., Burton on Trent, DE 14 2NF. 01283 534130 user@bbbbot.fsnet.co.uk. That was back in 2003, don't know if they're still on the go. Came in primer grey, with no holes. You had to drill in your own fixing holes from measurements from the old tinware. I had it for a few years before finally getting around to fitting it, only then did I notice it was a bit 'bananna' shaped, and was a bugger to fit. Once fully tightened in the frame the 'bend' isn't too prominant. Something to look out for.
