Momma's Certo Bottle??

[CCB420]

i had one of my customers give me a cpl bottles that her x husband didnt take along, after vacating the premises, and she was all too happy to let em out of her sight!! one of em has a handwritten note inside reading "momma's certo bottle"
myself, ive never heard of certo, dont know the previous owner so pretry sure i dont know momma either, but did think the bottle was pretty cool! i like the color, appears older, has lots of air bubbles, but im srill trying to figure out what is Certo?? anybody got any ideas as to the date and contents?

Certo is a fruit pectin brand that is still being manufactured today. The product was first marketed in the late 1910's-early 1920's. Your bottle is probably an earlier one given the unrefined automatic bottle machine imperfections and ejector ring mark, probably 1920's-40's.
