I don't know a lot about milk bottles . I am pretty sure some of them are dated on the bottle . As for it being an acl , my guess would be that it wasn't .
Yes i does have some embossing around the base it is 4 sided one side has 1268 REG. another side has sealed g in a square and an S another side says one quart and the other side says Liquid and the bottom has 14 54 so possibly its a 1954 bottle.
