The dairy was Sea Shore Dairy Farm / Sea Shore Dairy Products, operated by R. Woodson Jones & Sons at Townsend, Virginia, on the southern Eastern Shore in Northampton County.
The bottle is in good condition with very few flea bites and could certainly be tumbled to look pristine. Half pint bottles are much rare than paint bottles as they made fewer of them and they tended to break more often. This is an extremely rare bottle and hard to get in any condition.
