Old Amber Bottle

This is an old amber bottle that I dug up out of the ground. It is standing next to an IPhone 6 just for sizing purposes. Super excited about my bottles because this is what my siblings and I did when we were children. My sister and I stumbled on a hot bed of bottles, and I will be listing them as I can. This is just a plain amber bottle, do not know the date. The bottom of this bottle shows 18-S-B. The B could be for Brockway, as I have come across many other Brockway bottles. It appears to be a corked bottle, no threads, and the seams go over the lip. Bottle about 2.5" x 1.5" x 1". If anyone can help identify any of my bottles I would appreciate the input. Thank you.
