I could use some help identifying this bottle...

The only markings I can see (barely) are on the bottom, which look like a diamond with maybe a C or O in the center and a number 4 near the bottom-left side of the diamond. Here's a picture of the bottom, but it's even more difficult to make out by photograph.

Any help would be greatly appreciated!


  • This is a generic pharmacy bottle from the mid 20th century, most likely 2nd quarter 20th century. Made by a glass manufacturer in quantity, sold to pharmacists by the case who used them to fill prescriptions.

  • Thanks for the information! That makes sense given the nondescript nature of it.
