For a light weapons expert like Browning, Arthur naturally attached great importance and trust.
As long as Browning used all the funds for weapons research and development, what would it matter if there was no upper limit on the funds?
After all, the research and development of weapons wouldn't cost hundreds of thousands of Australian dollars a year. If Australasia could obtain an extremely advanced light weapon, it would be much more valuable than those few hundred thousand Aussie dollars.
It should be noted that light weapons are not limited to handguns and submachine guns. Rifles, light machine guns, and heavy machine guns are all classified as light weapons.
If Browning put it to good use, Australasia's light weapons improvement and research and development for the next twenty years would not be a problem. They would always be at the forefront of the world in military industry.
