Mystery Dragonware Tea Set

The item is part of a family estate. Unfortunately, no one knows when, where, or for how much this was purchased. The lid of the tea pot is inexpertly repaired, all other elements in quite good shape with minimal wear.

I've tried to compensate for my less than helpful description with good pictures, below.

I'm not opposed to selling this item, but I don't know enough to ethically set or correctly evaluate an offer. Not a good position to be in, so I'm inclined to hold off for more information.

Any idea of the provenance or value of this set? Any guidance would be appreciated.
