Andy,
No problem, looking forward to seeing your thread, I bought the bike in the early 90's, I rode it myself for 10 years, then I loaned it to my cousin's husband who raced it for a couple of years (how it wasn't crashed I'll never know!), I then loaned it for two years to a friend of mine who put a new headset on it. I finally got it back over a year ago and it was at that stage I checked the serial no. on it and discovered what I had. I knew it was a top end bike when I purchased it, but you didn't have access to the amont of information thats available now on the web and especially on forums such as this one. It a great time to be getting these old bikes back on the road. Best of luck with your build.
Regards,
Pat
