I don't know much about milk bottles but those look a bit older than the ones I've seen. Any other pics of the one at the top? WElcome to the forum by the way...I'm sure with detailed pics some of the members here can help you with additional info.
Cool. I thought the top one might have been a pickle jar. It looked like if had some flat sides vs. round (like the ketchup bottle at the bottom). Wish I could find some cool stuff like that in my shed.
