This is an Antique TCW & Co. Glass Apothecary Bottle with Glass Stopper that had contained SULPHURIC ACID, ( H2, SO4 ).
A little history of the company (TCW & Co) shows that this bottle was produced before 1901;

In 1888 Dr. Wheaton took over a local glass operation that had been struggling and rebranded it, initially embossing the bottles with the "T.C.W. & Co." trademark while establishing it to produce pharmaceutical and scientific glassware.   

In 1901 the firm dropped the ampersand and came out with the T.C. Wheaton Co., and re-establishing itself as a leading supplier of prescription bottles, lab vials, and perfume bottles.

The bottle itself is a little over 5 inches tall and in remarkably clean condition from the deeply embossed raised block lettering to the ground-glass round stopper that fits snugly into the ground-glass neck. It is marked TCW & CO on the bottom but hard to capture in a photograph.

Please look closely at the pictures and ask questions if unsure about anything.
