Scales (embossed image showing a pair of weighing scales)…………. Trademark used by McKesson & Robbins, a pharmaceutical / drug company. Originally Olcott & McKesson of New York City, founded in 1833. Business name was changed to McKesson & Robbins in 1853. Other name changes/mergers over the years, currently (2017) known as McKesson Corporation. Many bottles and jars with this design on the bottom seem to be products of Owens-Illinois Glass Company. Often seen in bright emerald green or “Seven-Up green” glass. I don’t have a timeline when this mark was used on containers, but most of the examples I’ve come across seem to be from the 1930s-1960s era.
Oh thank you. This one was driving me insane out of curiosity. I thought squibb at first, but then that didnt match up. Using broken pieces in a craft project and saw it. Time line is spot on for the junk pile.
Thanks again.
