Just did a bit more research.
The Sectional View I showed in the above post from a 1901 Remington Arms Co. catalog was used from the October 1894 Remington Arms Co. catalog which introduced the Remington Hammerless Double through their second 1902 catalog. This is the Sectional View shown in the 1903-04, 1904-05 and 1905-06 Remington Arms Co. catalogs --

There is no Sectional View shown in either of the 1906 Remington Arms Co. catalogs or their 1907 catalog. In the 1908, 1908-09 and 1909 Remington Arms Co. catalogs the sectional view shows the new style action with the separate firing pins and the repositioned sear pin.
