A little closer and I'd be there.
1860's or 1870's English blackglass. Beer bottle. Quite common.
$10. Without the label these bottles are nearly worthless unless they are an unusual size or color.
I've only got a few bottles, but saw this one at the flea market and loved the color and shape. Trying to identify its age and it appears to be quite old, but I'm hoping for additional opinions....
Early machine-made bottles tend to be pretty crude...I have some that are cruder than hand blown stuff from the same time period.
