What do I know?
Turns out we are not keeping the china. Rob has no emotional attachment to it so if his sister doesn't want it, we'll have to find someone else to take it. I have no idea who that might be, but I definitely have no intention of selling it on e-Bay. I imagine we can find a collector or dealer here in town. The only person I found on the web looking for this pattern is in Missouri and that means packing and shipping - ugh.
