Correct Nando,
Butttt, the first one is more for the pictures and measurements which are understandable for anyone familiar with the Arabic numerals
The little German that remains is easily translatable for people of intelect, of which i know you are one Nando
It can't be all as easy as reading Portuguess, hehe
edited: ps the pictures are mostly under "kanonen Kugel" and than scroll down because the pictures are not directly next to the list of different types of cannon balls.
