Does anyone have dating information (range of availability and/or use) on "London"-shaped soft-paste white earthenware bowls?  These are the usually medium-sized (c. 15cm rim diameter by c. 10cm tall) footed bowls with a straight-conical upper cross section, truncated by a steeper cone toward the base, then flaring out to a robust, everted and usually rounded (in cross section) footring.  They may also have some flaring on the rim, though, to be called "London" (probably not a completely accepted term), the rim should be straight with the major cone of the body.  Annular/mocha and transfer-print decoration is most common, though plain/undecorated examples are also well known.  I know these as "early-to-mid-19th century," but would like to get more specific than that for a domestic site at Fort Drum which has a number of them.

Thanks,
