Not really sure as to it's exact purpose, Wolfie, apart from the fact that it seems to be some kind of stand.
Bears many similarities (foot, base, finial arms, upper ring) to this superb quality hand-blown lead crystal dish bearing the registry date lozenge for 19 October 1867 - Parcel 4, showing that it was from design numbers 212674 to 212677 registered by Thomas Webb & Sons Limited.
RD 212674 was design for a handle, pouring spout and feet (in this case apparently adapted for the supporting arms with splayed and reeded ends).
RD 212675 was for an applied shell-shaped prunt (matching the designs in 212674).
RD 212676 was for a variation in which the handle in RD 212674 was attached at its upper end.
RD 212677 was for an applied circular radially reeded prunt.
