In Cambridge bikes go quickly even if they are tatty more so any bike not locked up, which are then just used to the destination and dumped. There are in fact many bikes in the city that are left and then used from one person to the next as and when . That saddle, if it is a Brooks, would go quickly too as would any QR wheels if not cable locked.

PS thanks for the pics. It does not look bad to me and in fact appears very functional and well laid out.
