The NEW RAPID shell was first produced by the United States Cartridge Company in the late 1890s. The recessed (or grooved) head version came along around 1900 and was produced until 1910 when the NEW RADID shell was replaced by the AJAX. While the standard black New Rapid shells are pretty scarce, the tan variation on the right in this picture is quite rare. It strikes me as odd that USCCo would have produced a tan shell when ‘The Black Shells’ were the focus of their advertising.
