Thanks for the info! What is the determining factor from the 103 to the 104? They look almost identical, except didn't see any 104's with the applied lip like on mine... does this change the glass maker venue from Whitney or Ravens to a different maker? Thanks, it is crappy to not have McKearin's bible and aimlessly pursue the (already known, researched, and documented) amazing history depicted in these flasks.
The lip is important to some collectors but that was just added later at the the makers option most often (sometimes ordered a certain way).The mold is what distinguishes it from the others and there have been many new ones found since that book..
