Does anyone know where I can get a clock winding key ?

Quicktest.co.uk or one of the many clockmaker's suppliers.

There are many sizes. If you have a vernier caliper you can measure
this and buy the correct one. Otherwise you can buy (cheaply) multi-
size "spider" keys. However these usualy come in sets of two: odd
sizes on one, even sizes on another, so you need both to guarantee a
good fit.
