Please check out the association between pilgrim glass wv, and the collaboration with the moretti brothers from murano Italy. I'm happy to own this little piece of history. All who have seen, have agreed, that is a pilgrim pontil mark aka strawberry pontil. When I the expose the ashtray and article that tied it all together the pilgrim experts clamed up. I got no "absolutely" yes from the pilgrim Facebook group regarding the latter exposed whole piece but everone chimed in regarding the scar. You dont know how much that bothers me. I have done hours of research to make this connection but there is no "pilgrim glass" today to confirm my findings.
