Having been pinged by a very helpful retrobike user, I will try again - this is apparently worth £200. I interviewed Joe Murray many moons ago for Bikeradar when I did a spot of journalism. Nice guy. There's some small rust on the frame and pedal clips. Some additions over time, I used it for commuting up until 2003. But it's gathered dust since. I measured the size from the middle of the bottom bracket as 17 inches. from the bottom of the bottom bracket it's closer to 18. Maybe it was 17.5? I don't know, I've slept a lot since 1992. And it depends on where you measure from.
