sorry, but I'm probably out of my depth with this one, and wud appreciate some help please. Can't post a pic. because the piece is still in the charity shop, and being held for me till tomorrow. Description is: conical flint vase 220/230mm tall - top opening of about 110/120mm - with pronounced 'rings' around the cone - about 4 or 5 in number. Base is circular, mostly mid green, a good 10 - 12mm thick - about 80 - 90mm wide, and with a large very professionally ground/polished pontil mark. And here come the bit I don't know............scratched into the center of the pontil area is the following: "o f" (then underneath) "lw 108".
The base wear is considerable - enough scratches to make me think half a century perhaps, and my thoughts (for what they're worth) was Scandinavian. Wud appreciate any suggestions or help please, and thanks for looking. Paul S.
