Yep, mistype. Meant the 37mm, not 47mm, lol...although there was a 47mm Pak 35/36 (ö)...
And yeah, I'd love to hear the reasons that a Sherman had better armor protection than a PZ-IVH or the T-34. Type of steel, hardness (homogenous, rolled, ect...even different types of welding methods and plate overlap), slope, ect...even the areas of protection would be important.
