Just on the off-chance anyone is interested, a colleague I work with has a number of the early Clarecraft Discworld figures he is looking to get rid of.
He's planning to put them on e-bay, but I thought I would mention them here first just in case anyone is interested.
The figures he has include the three witches, the Night Watch, and Teppic the Assassin. If anyone is interested, drop me a PM and I'll send you the full list.
