Is/was the leather strap around the neck glued to the glass? How about the base leather? I recently got a hold of a proper George Dickel bottle (right size and color of glass), and the base leather is either glued on or stuck on with age, while the neck leather is loose but shows signs of having been glued or stuck with age at some point... I can't tell much from screencaps from Enemy Within, By Any Other Name, and Journey To Babel, although it looks like the neck was loose in By Any Other Name (before Scotty and his guest get to the bottle of "it's green").
