Found one! Via the LFGSS forum. Didn't pay too much for it, certainly less than eBay prices. Colour scheme is "quite interesting" - 1995/1996 purple, yellow and green. At least it's not blue or silver like my other bikes!
Going to build it up with almost period correct Ultegra 6500, but with Dura Ace 7700 down tube shifters. I haven't used down tube shifters since I was 15/16 (20 years ago), as a rode fixed when I "returned" to cycling and now have Campag Ergos on my Bob Jackson. Hopefully I'll be able to remember how to use them effectively!
