Knowing the maker is essential, unfortunately many do not mark them. I have several great Meers with no makers mark.
Carver/manufacturer is everything. Meerschaum is not rare, or even uncommon....it's extremely plentiful, even in it's highest grade.
Anyone who has spent time in Turkey, or other ME countries can tell you, there are a LOT of Meerschaum carvers. There are entire towns where Meerschaum pipe carving is the main occupation. It's not uncommon to find very old(18th century) pipes on ebay.
So, in my opinion, this piece may be an interesting museum piece to "normys", but without a story or legendary maker, it's just a busted old pipe to pipe smokers......in my opinion.
