ORIGINAL: Monter_Trismegistos 370mm (BTW I never heard about this calliber - was it a naval weapon?), 340mm, 65mm seems bloody round callibres for me. These are normal callibres for metric system. No, the French Navy apparently never planned beyond the 340 mm in WWI, intending to use twelve in quad turrets in the Normandie class (one of which was completed as the carrier Béarn) and sixteen in quad turrets on the Lyon class. The 370 mm was used as a railway gun, both in WWI (by the French) and in WWII (by the French and the Germans). It might originally have been designed on spec for future ship designs, but I have found nothing else about those guns. The thing concerning "round" calibers was perhaps awkwardly expressed. What I meant was that nearly everybody used inch-based calibers or at least metric calibers close to them (6 in vs 150 mm, 15 in vs 380 mm etc). 340 mm is close to 13,5 in (343 mm), but 65 mm is 2,6 in and 370 mm is 14,6 in, both outside the usual range of gun calibers. Perhaps the French value originality above everything else, even in technical matters. Looking at, for instance, Citroen cars, you might certainly think so, and there, it´s both a blessing and (more often) a curse.
