The 10.5cm gun, the same as in the Strv 103 with 62 caliber length instead of the shorter in the centurion, just with a different auto loader, like in the French tanks.
Oh, and I forgot to mention a fluke by gaijin. The Strv 103 C’s Slpprj m/80 should have a higher velocity due to the longer barrel, and more acceleration time, therefore having more penetration.
The 105mm gun option was originally meant to be 67 calibers. It, like the 150mm option was an entirely domestic design (to be based on the 105mm Lvkan m/43), completely unrelated to the L7. Some discussions were held to acquire a foreign gun, but it never materialised. Though it seems the gun was later changed to 62 calibers.
It’s unclear how development of the 105mm was going, and if it was even considered for the project past 1954. It’d be interesting if it turned out to have developed into the gun fitted in the Strv 103.
The Strv K with Centurion Mk.10/Strv 101 turret is the only option for implementation, as all parts were built. Some large modifications had to be done to the turret ring and internal stowage, but we’ve already got vehicles that were as uncomplete in game.
