Named after the Spanish Civil Guard, but never been proven to be issued to them. Essentially a Spanish Model rifle, with two bands and 30.5" barrel, all chambered for .43 Spanish cartridge. Many were sold to Cuban volunteer regiments serving Spain, with most found thus far with a number stamped on the wood at the front tang of the buttplate. Numbers appear limited and were advertised in factory catalogs dated as late as 1882. Ironically, records show Argentina procured a small number of them. Rare.
