I have decided to sell this early saracen, it is new old stock and unused. Located in Wisbech. The listing is Scheduled to be live at about 20:10 This evening. I will add a link when it is live.
It's also used for a "not quite bottom of the range" MTB groupset from the early 1990's. Admittedly most of the bikes fitted with it weighed about as much as a ship, so your comparison is not wholly inaccurate
