I've seen backwards letters, but never the letter "Q". Those are some very nice Texas pharmacy bottles, 109. Here's one of mine that some of you may've already seen, with a backwards "N". "Chemists" is an archaic term for pharmacists and druggists.
Wow, that's one absolute beauty of a bottle! I don't think I've seen that one on here before. Alabama isn't a state I normally associate with early pontilled bottles.
Thanks much and I hope BF109 will forgive me for throwing it on. And not to change the direction of his thread, but for anyone's benefit that might be interested, there are a few, all extremely rare pontils from Alabama. Mine is probably the most common, with no more than 7 examples, all varying to some degree in color, lip finish, etc. The aqua IP Talledega Sulfur Water: one known. The black IP gallon Bailey Springs Water, Florence, Ala.: one known. The emerald green IP Saunders Compound Syrup of Styllingia...Mobile: 2 known. And you're right in your thinking because Alabama was such a poor agricultural state at that time with little commerce and industry.
I agree that it would have to be difficult either way to cut any lettering or decoration into a mold, but iron molds were used in most commercial bottle production. Wood will work for the short term, but will not hold up the the repeated impact of the molten glass over a long period of time.
