It might be me, but 3 millimeters seems rather short...

Har har, its obviously a typo.

OK, the first 25mm is the French 25mm AT gun from history, but what's the second one? It's gained a 50% longer barrel, but lost almost 40% of it's weight, seems an unlikely combination.... And even with the gain in barrel length and a new cartridge case, it doesn't seem to have gained much velocity. (Assuming that the number after the first / is the barrel length.)

The second one is the 25mm Puteaux anti-tank gun model 1937.

Ah, the 25mm SA 37. Where's the "108" in the Atlantean designation come from, then, it's got a 72 caliber barrel, just like the 25mm SA 34?

Its a typo, and wrong too I suppose. Its supposed to be 180, but thats based on barrel length (1.80m). The caliber is listed as 25x194R mm under the French specs.

If you were using actual length, vs length in terms of bore, both 25mm AT guns would have the same "180" designation, since they were both 72 caliber weapons. Both weapons also fired the same cartridge, the 25 x 194R mm.

I've edited my wordpad file to list both guns as "180's".

Any other nitpicks worth noting?
