The salient features of these late Norman flowerpots are -- Slimmer bodies -- Round shaped string rims as opposed to V shaped -- Very big chunky glass blowpipe pontils -- No vivid bottle green colours. The diameter of the shoulders are between 9 and 10cm whereas the earlier bottles are between 11 and 12cm. The weight of the bottles are considerably lighter. As for dates, I would say from 1760 to probably into the 19th century. These bottles come with iron pontils too.
All four bottle were bought from Normandy, 2.131- 2.132 and 2.133 come from the same cellar that also contained double string rim varieties ( see next page).
