the gas pressure (as well as the impending end of World War II) led to the cancellation of this order. Despite this, Saive (who had returned to Liège shortly after its liberation in September 1944) continued work on the rifle, and finalized the design for the FN-49 in 1947. The FN Model 1949 is not ammunition specific, since it has an adjustable gas port or valve to adjust the rifle to various propellant and projectile specific pressure behavior, in which the gas port can be adjusted with a special wrench. This also requires removing the upper forward handguard for the adjustment. Production lifetime The contracts for the SAFN 1949 rifle started in 1948 with the first order placed by Venezuela on March 31, 1948, delivered exactly four months later. The last production contract of complete rifles was ordered by Indonesia on December 19, 1960 and delivered by February 19, 1961. Some sources claim pre-production models for demonstration and testing were produced in 1948, making rifle ready for contract orders and mass production. Other sources however claim the rifle was trialed with the Royal Netherlands Navy in 1947, The Netherlands Navy trials did not however lead to a sales contract. FN started looking for customers, but the communist states were not an option (as they were required to buy or build Soviet designs). The Western European nations had vast stocks of World War II firearms. They also could get American and British weapons aid, which was inexpensive or free. So FN decided to market to the non-aligned countries, who did not want to commit to Western or Soviet doctrine, which was inevitable when accepting aid. The first contract production of the SAFN 1949 rifle was delivered to Venezuela by May 31, 1949. It composed of 2,000 rifles in caliber 7×57mm Mauser, with an additional 2,012 rifles including cut-away training demonstration rifles delivered by July 31, 1949. The remaining rifles of the Venezuelan contract of 8,012 rifles were sold as surplus in the United States, and are prized by US collectors, sportsmen, and hunters because of the unique features ordered by Venezuela, the general good to excellent condition of the surplus rifles, and the superb accuracy of the 7×57mm Mauser cartridge. The second contract was for the Egyptian government, consisting of 100 rifles chambered to fire the 7.92×57mm Mauser cartridge (also popularly known as 8mm Mauser). It was ordered on May 30,
