It's a good un, it is shining up well with T-cut, although there are plenty of scratches and scrapes. It is very comfy and compliant to ride, even with the skinny tyres - something to do with it being a big frame maybe?
Nick, I completely forgot to stick up the serial number - it's NL 2002198 - I think that makes it a Nottingham bike with an August 1982 build date?
