ianhouts A bottle was dug up in Portsmouth, England with the letters NMM pressed in the base. Can you identify the bottle and explain the meaning of the letters? Many thanks
Chris I have been asked about this NMM mark before (see https://forum.antiquebottles-glass.com/search?Search=nmm) Unfortunately, the main reference of bottle markings ( Toulouse's "Bottle Makers and Their Marks" ) has no info on this one.
