Dave,
I'm told that this was Edison's second generation bottle. You may remember that Edison produced a unique battery oil in those now popular small glass bottles. It's described as " a pure nonconductive oil that is added to the potassium-based electrolyte in old Edison nickel-iron batteries to reduce water loss due to excessive gassing..."
Tom used the same research to reduce "excessive gassing..." from drinking beer which gave the glass bottle a magnetic property allowing the drinker to hold the bottle without touching the Edison name.
On the other hand, there is evidence that the photo has been modified by a rookie
