Hello all, just picked this beautiful open pontil medicine up at the flea market. It is embossed with an "M" on the lower front of the bottle. I found one online with the same mark, and an estimated date of 1860. Alas, no info on the "M" mark. Any experienced pontil collectors recognize this mark as a known glasshouse mark? Just trying to figure out where it was blown and if 1860 seems accurate. Many thanks--Joe
