This from an area where the maps showed a house in 1920 but no house after that. I suspect the vicks bottles were later on, but don't know for sure. Found a WWII button also, so I just don't know as far as the age of the site.
The third one down is from the owen illinois bottling company. The number to the right of the logo gives you the year the bottle was made. I can't really read it well over the internet. The second one down is from the brockway glass company. I would say the bottles are probably generally from the 1950's.
Thank you, Beyonder for that useful information. I think there are older bottles there someplace. When I dig into that bank there is like a 6 or 8 inch layer of soil that has some broken glass and an occasional bottle. Under that is packed clay with no glass fragments. There is a flat ledge then another bank so I have to check on down the hill.
