HA! I was a little inebriated late one night and created an eBay listing for the second one I found. I was offered a very, very princely sum for the first one I found, so I set my start bid, reserve, and BIN price ridiculously high as a test.
Ultimately the true test fell on me being unwilling to let go of something that the universe gave me, and I deleted the listing the next morning because the two bottles looked so nice standing side by side on a shelf in the early morning light. I'm not a hoarder, I just collect EVERYTHING.
After my actual work was done today I drove across town to do a quick site walk. I found this one there today in the sidewall of a large soil stockpile.
And get this: there was a broken Eye Water bottle not 6" from this one!
Yeah, I have 3 now, and this is the nicest of the 3 condition-wise (PERFECT), but the lettering seems a little cruder.
Anyways, I jokingly believe that I'm the global market share controller of Dr. J.S. Rose's Eye Water bottles, with 3 of the 4 known to exist on the collector market on display in my kitchen. Or so my research has led me to believe.
Regardless of what I think I may know, I picked up an accidental new hobby with some seemingly extremely rare unexpected jobsite finds. And they keep turning up one by one.
