85mm identification

Afriend of mine brought over some pictures of an empty 85mm shell. I tried the search on here but nothing related came up. It is marked 85mm HEM. there is also a kind of upside down “u” with a triangle and an F laying on its back, an arrow, and the numeral 1. The primer has three notches and some numbers that are too corroded to read. He measured the length at 24 and one half inches.

Edit    Tried to add an image but it didn't work? so here is the link

hehe I forgot to put down that I would like to know what it is and what country it came from. Sorry about that. The owner got it from Tanzania during the late 70’s

To my limited knowledge this should be an Iraqi case for the Russian/Soviet 85mm gun series D-44 etc.
