Tank vs. Cannon

22mm of WWII armor steel should be around DR 60 (penetration is normalized for RHA being DR 70/inch, and I would expect early tanks to be comparable to RHA).

Not sure about the penetration of the 12 lb gun, though. You can essentially view it as a 144 weight (5.24*scale) 12 gauge shotgun (12 gauge means a spherical lead ball would be 1/12 lb, 12 lb means a spherical lead ball would be 12 lb), and 12 gauge slugs are generally stopped by level IIIa armor (DR 12), so I'd be tempted to assign a (0.5) armor divisor.
