Hello! I tried to identify 2 military metal-cased cartridges. Both are identical except the inscriptions and come from the same place. Unfortunately I was not successful. I kindly ask you if you can help me, by giving some information about these two, especially about the second (year, manufacturer, if it was used in WWI or WWII). I attached 3 pictures with them. First seems to be clear (made by Scovill MFG. Co. - an american company in 20.12.1916 with metric designation (measured by me) : 75x384 mm), but the second, I have no idea. Thank you so much for your help.
