A picker stopped by last week & sold me a few bottles one being a Hostetter's . I don't remember an H-195 Dr. J . Hostetter's / Stomach Bitters with A & DHC / M on the base . I know A & DH Chambers ( 1842 - 1886 ) made many bottles and I've had W. MCG & Co. , AGW , S. McKee & Co. , J & W , L & W , etc... on the Hostetter bases , but can't remember an A & DHC / M on the base of a Hostetter's . I looked in Ring / Ham & supplement , but didn't see it listed with other manufacturers .
