I was thinking this was possibly a Scandinavian piece by Vicke Lindstrand, although haven't been able to find an exact match for this design, attributed to Lindstand.
It does seem to have similarities to other Lindstand pieces such as the one in the link below.http://pafemtevaningen.com/store/sold-items/vicke-lindstrand-1800-sek/
The colour appears smoky grey, however, when holding up it up to the light the colour is actually a light violet/indigo colour. Appears very well made and finished, ground base, with polished concave pontil mark.
Measures 11 inches tall.
All thoughts welcome.
