The inscription has previously been recorded as "1669. Hen: Sutton fecit."
Sutton was dead by then so this raises an apparent problem. However, on inspection, the 9 turns out to be a 0 to which a descender has subsequently been added. This seems clear by comparison with the forms of the 9s on this and other Sutton instruments in the collection. Especially striking are the size and proportions of the circle of the 9 in the date of our two Sutton instruments dated 1659.
