Time for some guns pr0n, for the ammo and guns of 19mm and under.
The time specified saw the wast amount of resources and time invested in all things military, including the small arms. Americans almost adopted the .276 Pedersen, Italians made more of their 7.3mm idea, French switched from the rimmed 8mm to the rimless 7.5mm, and there was also a number of intermediat cartridges that actually mattered. The 6.5mm ammo saw the upgrade from round-nose to the spitzer bullet, but not everyone took the opportunity, and the 6.5mm all but died off after 6.5mm as a mainstream military cartridge.
Above 10mm, the 12.7-13mm cartridges and weapons were omni-present, while 14.5-15mm were also used, but at the far lowest scale.
Pistol calibers were also diverse, more than it was the case today as far as the military cartridges go.
Infantry eapons went from repeating guns to the semi-automatic and at the end to the fully-automatic weapons.
What might've been the alternatives to these developments, and was there some weapons and/or ammo that warranted a second look? Steal the idea from a friend or a fow? Double down with something that was, in perspective, an advantage? Granted, there will not be the 'one size fits all' to happen, nor everyone will have the resources to diverge a lot from what was made historically, but still.
I'd start out with two, IMO, obvious changes - Italians forget the 7.3mm and 8mm Breda, and go with existing 7.7mm and the spitzer bullet for the 6.5mm. Together with 9mm, that overs all the small arms needed, from rifles to thick-barreled MGs for vehicles. Saves them a lot of money and time, while improving the overall firepower. Of course, make something else instead of the good-awful 6.5mm LMG.
