"Cow leather is so thick that it is usually split into two usable parts. An un-split cattle skin has a thickness of about 45 millimetres."
45mm = ~1 3/4"

I am a little confused by the info in this article. Having skinned more than one cow, I could not state that the hides were anywhere near 1 and 3/4 inches in thickness. Perhaps up to an inch in the neck area but the main cow hide(back, sides, belly) is thinner than 1 and 3/4 inches.
I am not dissing you, Patrick, but the info does not match what I have removed from cows we slaughtered.
