The woman at the boot sale said it was Ravenhead, but I have looked around some, although not able to see anything like it (cud be looking in the wrong places, of course).
Mould blown, with four seam marks, and shading from greenish at the base to amberish at the top - and about 8"/200mm tall. I may have goofed with this one possibly, and don't believe I've seen one previously :huh: Thanks for looking and grateful for enlightenment if anyone does recognize the design.
