UPS happened by yesterday: annoyingly I was in London. So I took a work from home day today, and, wonder of wonders, UPS rang the doorbell and didn't actually just shove a card through or dump the parcel on the step.
Pity they didn't take more care of it in transit, though....
Fortunately, nothing inside appears to have been damaged.
The box is very densely packed, and I may have my work cut out over Xmas getting it sorted and some of it painted, I suspect!
