Only found a little info on him. Can't pin down when he started, but in 1896 the Ryan Drug Co. merged with the Pioneer Drug Co. With Mr. Ryan as manager. So I would assume your bottle pre-dates 1896. Any embossing on the bottom ?
John, it is circa 1885, listed as Scarce by David Bethman and should be valued at $50 up. BTW, I'm pretty sure it's not actually pontiled, perhaps rough on the bottom. Jim
Hello John. And the WT on the bottom is for the whitall tatum glass mnfg co of I believe Ohio, they had a lot of glass factories and made zillions of all types of pharmacy bottles for a very long time, over a hundred forty years, and they are still going.....Andy
