Here is a really nice pony or squat blob top from Ashland PA, from the Schuylkill county coal region. I practically spent 1/4 of my life up in Ashland. In the past two recent years, I've been finding excellent spots for glass that I have to check out.
Ashland holds a special place in my heart. My ancestors lived and did business there. My grandmother lives there now, and It's one of my favorite towns just to walk around. It's gone downhill over the years due to the drug crisis, just like any town nowadays.
As for the bottle, this is 1865-1875 from first look. I am unable to find any info on it other than that. I know my grandfather and uncle dug these up by the dozens in their privy digging days, but they sold those along with everything else to make money back then. My guess is it's beer, because there were countless other beer companies in the area. The miners had iron stomachs from what I could tell, lol!
