The blueprints and data that Shire provided to Tijani are for the "Agile-class" destroyer that France developed nine years later.
Everything else is the same, except that the two single-barrel 37MM anti-aircraft guns were replaced with ten 20MM machine guns.
Although it started construction in 1925, the two 37MM guns used are called "French Hand Crank Machine" gears, with a maximum rate of fire of only 30 rounds per minute and a combat rate of fire of less than 15 rounds per minute.
(Note: The "Agile-class" was built shortly after World War I ended, and the French Navy did not yet have an emphasis on anti-aircraft defense, so these two 37MM anti-aircraft guns were more of a last resort than a strategic presence.)
The combat rate of fire for the Oerlikon 20MM machine gun, however, can reach 320 rounds per minute.
It is well known that anti-aircraft defense relies on a barrage of bullets to hit the target, and the rate of fire translates to a higher hit rate.
