Oh yeah, I won't say how old I am, but my mom used glass baby bottles...not as old as this one though. There a few numbers on the bottom that I can't really make out, the ounces are imprinted along the side.
Lots of old bottles dug up in the old outhouse locations, Some people up here are good at tracking those down. But, just walking our property after some good storms...some do get uncovered, and those are broken. We live where they just dumped stuff..all over the hills in the late 1800's.
