See six images, each with click main image to enlarge feature, via
http://glassgallery.yobunny.org.uk/displayimage.php?pos=-19953H. 7" 17.5cm, w. 1lb ¾oz 478g, interlocking 14 spot pattern repeat (jar and lid), rims ground flat, lightly chamfered, and polished, three-way (Y) shear mark to base of jar.
No mould lines visible — it looks to me as though the shape moulds were steam lubricated with the glass being rotated in the mould.
This pattern seems to be what Bill Heacock terms either Coinspot or Windows. I have his books 2 and 9, and found another 14 spot pattern repeat on a Windows tumbler at 312 in Book 9. Both books warn about reproductions, so I am not unduly optimistic.
Lots of apparently genuine light wear on the base.
I would be grateful for any information on this nicely made jar.
Thanks for your interest,
Bernard C.
