The bottle is not perfectly square on the bottom, so it wobbles a bit. A portion of the cork is in the bottom of the bottle, along with some dry ink dust. It seems the company started in the mid 1800's and was still in business in the 1930s/40s. I didn't have a lot of luck with this research, nor do I know the age of this bottle.
It says For Railroad and Express Co's use. Measures approximately 7.75" tall and 3" across the bottom. Weighs just under 1.5 pounds.
