Very funny! It it wasn't for the issues with ammo going on. I'd happily send half of it was more than I'd uncomfortably shoot my k98. So gentlemen it's definitely 8mm mauser?

I suppose you don't have a dial caliper? Easy to measure the bullet at the case mouth and the length of the case. IE... 7.92×57mm Mauser - Wikipedia
I know I was a builder/smith for a shop before i moved. Had all the tools at my disposal but was very rare i got to work on older rifles. 8mm isn't something i can visually tell. I may just go outside and fire a couple rounds and hope for the best. I'll update tomorrow!
Egyptian ammo is very corrosive.
We used to joke that is was so corrosive that you had to clean between rounds':)
CLEAN WITH WATER AFTER SHOOTING! Bolt face too.
Then regular clean and lube.

The 30-06 and the 8mm are all corrosive primed. FN did not switch over to non corrosive till half way through 1958. Now the 8mm could be Egyptian or it could be Iranian which has a lot of click.....bang or just click. Lot of that was floating around a few years ago.
