Tea pot ID help please. This was made by David Griffith

Hi all - A quite refined tea pot - very well made. The mark is a circular stamp - a wheel with 8 lines with a small circle in the middle. I've been through the gallery and I see Barry Brickell used a circle but this does not look like his style or mark which is a bit more rustic? Many thanks for any info.

Hi there, this is the distinctive work and mark of David Griffith

Thanks once again Ev - it is so well made
