i dont want to disagree with harry, but the applied lip on tha piece looka a bit more crude than the 1880s pickle bottles i have seen. i just have a feeling it is 1870s or maybe even 1860s... correct if im wrong though.
I think 'gleaner1' is correct. These pickle jars became less and less ornate as time passed. Pontil-scarred, ornate, often green jars in the 1850s transitioned into the graceful, but unadorned jars of the 1880s and 1890s. Here's an example of a smooth-based, somewhat ornamented jar from the 1870s.
The transition of these pickle jars may have been more abrupt than gradual. I checked The Bertrand Bottles (steamboat sunk in the Missouri River in April of 1865) for cathedral pickles jars. There are a good number of ornate molds represented, most of them familiar from bottle auctions.
