Olive oil was bottled in an assortment of different shaped bottles during the era (early 19th to mid-20th centuries) with most types being cylindrical or round in cross-section. These type bottles are tall and narrow, being at least 3 times taller in the body than the width. It also has a crudely tooled (or possibly rolled and refired) finish, a crudely pushed up base (over 1.5" from heel to top of the push-up/kick-up) that is off center and obviously not mold formed, and a visible though slight splaying out of the glass near the heel. This latter attribute is often indicative of free-blown manufacture, although some dip molded bottles can express this feature if the glass was still plastic and "flowed" after withdrawal from the dip mold.
A double ring finish has two-part finish is composed of two connected "rings" - a thicker (taller) and slightly wider (side to side) variably rounded ring at the top of the finish (the "lip") with a thinner and narrower variably rounded to flat ring below (i.e., "collar"). The upper (lip) and/or lower part (collar) on this finish can sometimes be more of a pointed "ridge" with flattened surfaces leading up the "peak" of the ridge. When the upper part is rounded and the lower collar has a sharper outer edge this has been called an inverted double ring (Feldhaus 1987), ring with skirt (Blasi 1992), or broad round collar with lower bevel (McKearin & Wilson 1978).
