The Owens ring again covers the entire base and even intrudes out to the side of the bottle slightly.
In the neck on the right notice how just below the collar the mold seam goes complete around the neck. Both of these medicine bottles look much like their earlier counterparts.
This was the manner in which the early Owens bottles were blown. the step out collar of the example on the left is characteristic of bottles of the late teens and 1920s.
Note the diagonal line which cuts across the base is obliterated by the Owens Ring (the large off-center curcular feature). the base is crudely made for a machine made bottle.
Owens' early bottles were often cruder than their hand blown hand tooled counterparts.
The automatic bottle machine was much more precise in gathering an exact amount of glass and the same amount of glass for each bottle this consistency lead to more uniform products.
