A nice bone barleycorn set was acquired with an amusingly mismatched home-made King. Alan Dewey, the ChessSpy, was kind enough to source one for me which was a better fit.
The thing on the right has been put together from bits of a Selenus set, whose characteristic feature is (nested) crowns. Alan points out that they normally point upwards!
