Can you help please?

I’m confused here because the “I” in the diamond is longways. Illinois Glass Co. from what I can find went the other way? Machine made, 2 piece. These are the only markings. And when researching - are both of these bottles considered olive green? Thanks in advance

Your right about the mark. Odd, could be an unknown manufacturers mark. The one on the left is olive green. The other is not.

Thank you. And that is the one with the weird mark. Hmmm. Now it’s going to drive me crazy not knowing lol any idea of an approximate date? I’m thinking early 1920’s?

That large off-center ring on the base is typical of bottles made on early automatic bottle machines. Not all glass works got ABMs at the same time or upgraded at the same time. I have always considered bottles with that ring to be between 1906 and 1920, just because the ring starts to disappear in bottles made in the 1920s,
