HYBSON, WESTCOTT AND DUNNING small embossed bottle for mercurochrome.

This small embossed HYNSON, WESTCOTT and DUNNING bottle once held mercurochrome, an antiseptic commonly used in the 20th century.  The bottle would have a glass stopper/applier, which is not with this bottle.

I did not find when the company was formed.  They did produce a product, perhaps the same or different product, that was sold in a cobalt blue glass bottle.  I've not found one of those.

Here is a vintage or antique ad for mercurochrome.
