sea green is, I think, a fair description of the colour - so I reached for Leslie Jackson's book in the vain hope I might see this design. But alas no. This beaker really is lop-sided and measures 98mm on one side and 93mm tall on the other, and about 67mm wide at the mouth. As can be seen, there is a definite, but weak 'wrythen' pattern, and the base has a high quality ground and plished pontil mark, surrounded by some reasonable wear. The prunts are very wfrs. ish - unsymetrical - and the rigaree has ingrained dirt around the folds, which despite washing have not been removed completely - a good sign of age perhaps. Oddly, the inside of the base rises slightly, in the centre of which there is a dimple (some dirt caught in this) but don't think the pic. does this justice. So, Im stumped, and help needed please. My thanks for looking. Paul S.
