Thats not the document I posted, but I don't mind, this one is very interesting too.

Let me analyze it and come back to you once I'm done.

It is the same document. The number on the document is 1008 But the number on the site (LH pic)  is 1021. Once you have a reel number  it is very easy to find. 

the site  is https://heritage.canadiana.ca/view/oocihm.lac_reel_t17472/1021      and you can  just change the reel number/page number  (t17472/1021) to quickly navigate to another reel -if you know the reel number you want!  Most (but not all) are sequential so reel 17472 follows  reel 17471.  Not having an index means you have to look at each page to see what it contains but I did a quick scan through these reels and they mostly deal with Artillery matters but also tanks used as OP tanks and Armoured Cars to be used as Rear-Links, gas protection equipment, contracts for shells. ammo allocation stocks  etc. I guess it all depends how keen you are and if you have the time to wade through them all.

Yes, thank you, I see you have more experience with these online archives.

"reason to assume [...] entirely different", kek. I have a feeling that the results of said metallurgical report were not quite what they have expected. This just goes to show that even these historical document written by the experts of the time are not the absolute authority on these topics. 

They don't seem to realize that even the same armour plate can show different behavior when tested under different conditions. A glancing hit like this transfers less energy to target as the projectile ricochets with considerable remaining fraction of it, and the one that does get absorbed is spread over a larger area. The German tank designers clearly knew this, and have designed the armour production and quality control processes to get just enough toughness to resist such blows from overmatching AP shells. Whether this was the right approach is debatable, but it just goes to show that extrapolating the results of ballistic testing at low obliquity with overmatching shells does not paint the full picture.
