REMINGTON & SONS with 1874 as the final patent year. All have 35.5" barrels, except where indicated. From 1888 until the end of production, REMINGTON ARMS COMPANY marked on tang which reflects the reorganization of the company. Realistically speaking, any Remington Rolling Block rifle whether re-chambered or modified from other versions that were sold by the company or its agents Schuyler, Hartley & Graham, (which would by 1900 become M. Hartley and Company) in .43 Spanish caliber was listed as "Spanish Model". Listed are the four sub-categories in addition to cataloged generic variants manufactured after 1874 and priced accordingly.
