T.C.W. stands for T.C. Wheaton, manufacturer of apothecary bottles from 1888 to present date. This bottle measures 6 ½” tall and 2” in diameter. Raised letters denote the measurement in MILS. It looks like the bottle takes a stopper which is missing. The bottom of the bottle has the following verbiage, in raised letters “T.C.W. CO. U.S.A. M-55.”
This bottle is in mint vintage condition and other than missing the stopper (if there was one) it has no flaws.
