Here are some Hardman's High Grade Chocolate Milk bottles. These are fairly scarce. I have these two different pints. One is dated 1929 and the other 1941.
Here are two Dunloggin Farm Dairy half pint bottles. The one on the left has BCHD Milk Plant on the back and the other has BCHD Dairy plant. They switched the word dairy to milk in the late 30s.
Here are some ACL Dunloggins. I keep them even without paint. The two on the right are embossed on the base and the one on the left is not. With good paint these have been seen to reach $300+ . They are one of the most sought after milk bottles around.
Here are some more ACL Dunloggins. These would have had orange and blue paint and would have said Dunloggin Farm Guernsey Milk instead of Dunloggin Farm Dairy like the ones in the previous pic. They are also made by different glass companies.
The two on the left are Baker's Newton Farm Dairy and the broken one on the right is literally the only one known as its kind. It is an ACL Rockland Dairy. They were not known to have used ACL bottles until I dug this one up. What a shame its broken though.
Here is the last bottle and one of my favorites. It is the only square milk bottle from Ellicott City and it is mint and still has the cap. It is Baker's Newton Farm Dairy.
