I found a collection of parts for a set of uillean pipes on sale in a second-hand shop yesterday. I couldn't check the whole lot, which was in several boxes, but it may be a full set (bag is there) and perhaps spare drones etc. The seller says they came from the defunct Borough pipe band, obtained when he cleared items from a church. If anyone is interested, he is asking £60 for the lot. Let me know and I will put you in touch.
