It could mean a number of things. There's no real way of telling without knowing all of the markings on the rifle, and where this marking is placed.
The part of a map that explains what the symbols mean is called the "legend" or "key." It provides a guide to understanding the various symbols, colors, and markings used on the map, helping users interpret the information accurately. The legend is essential for navigating the map effectively and understanding its features.

Firearms International was an importer, now out of business I believe. It is unlikely that they would have actually marked the gun with their name before these markings were required in 1968. There are probably other markings that may identify the actual manufacturer. Double Action refers to a revolver mechanism and I have no idea what you mean by a doubleaction trigger on a rifle.
303 was the .303 inch diameter bullet that was fired by the Short Magazine Lee Enfield- or SMLE. Standard rifle of the British military from 1907 to the1960s, and still in limited use today.
probably proof markings
The markings on a bolt head indicate its grade, material, and strength. These markings typically include numbers, symbols, or letters that denote the bolt's tensile strength and other mechanical properties. For example, a bolt marked with "8.8" signifies a medium carbon steel with a specific tensile strength, while additional markings can indicate the manufacturer's code or specific standards met. Understanding these markings helps in selecting the appropriate bolt for a given application.
