I bought these bottles on Thursday in Lexington Kentucky. I was in a massive antique shop booth, that had well over 1,000 bottles. I have never seen so many in my life. The shelves were packed floor to ceiling and even on the floor. Sodas, meds, flasks, beers, blobs, ACLs, you name it, he had it. I could have spent weeks in there picking out bottles, but I only had minutes, so I picked these. I brought them home, and I can't find a single match to any of these bottles.
My best guess to the MB.CO bottle, is the Madison Brewing Company. I have only been able to find amber colored crown tops though. It has the Streator glass company logo on the bottom.
I can't find evidence that the cloudy looking bottle even existed. It is embossed: Bluegrass Bottling Company / Trade Mark Registered / Lexington Kentucky. It also has a "B" in a wreath looking thing. I can't find a Bluegrass Bottling Company anywhere. Puzzling.
The Engel Bottling works isn't such a mystery, in the fact that I know they existed. I can't find any pictures of a bottle like this one though, and I have no clue as to how long they were in business in Cincinnati.
I doubt they are rare, or worth more than the $25 I paid for them, but they are puzzling. At least for me.
