Valentine was a good machine. Outdated by 1942 against the Germans but useful against Japan throughout the war.
The Panzerkampfwagen IV Ausf F2 of later 1942 had a high velocity 75mm L/43 cannon and could engage T34s at reasonable ranges. The PzKpfw III Ausf L/M of 1942 had a high velocity 50mm L/60 gun that could destroy a Valentine easily at maybe 800 yards.
A Valentine was not in the same class as those two machines. The late war English A41 Centurion with it's 17 pounder high velocity gun was a full match for a Tiger. In Korea the Centurion made scrap iron and mincemeat out of T34s easy as fishing. Nearly.
Ain't Google handy? I have forgotten the numbers after all these years, darn.
There is a fully restored, I mean fully restored, Tiger at the RTR. Armor fans owe themselves to visit
