Anyone Familiar With A.T. & CO. ( not AT&T..which is every search) ?

The glass has a rose tint to it now from exposure, it looks like. I'm wondering if there are more below the surface but I've never heard this company, someone else maybe does? With the many variations of letters & Co.. I checked the antique bottle database and the EAG museum- which got me exited briefly with a company name- It was in SF, Cali. They were all dark, colored glass bottles with an unusual neck and the embossed design was in cursive..and Co. name was on the side . I'm a New Englander. I'm thinking it's probably something more local but who knows.
