9mm round without headstamp

[koldt]

Can anyone supply some info as to; manufacturer, year, who used, etc, for some 9mm ammo with absolutely no headstamp marks. Ive got a few rounds but nothing worth shooting, just for examples.
Brass case with FMJ blackened bullet and case.
They appear older 40’s? vintage. A photo would just show a 9 round.
Thanx.

Possibly Czech ammo for non traceability supplied to various nations including African . I have some 8mm Mauser like that. What kind of primer (material/look wise).

If you really want to know a photo over on cartridgecollectors might help you, there are enough sterile 9mm loads you need a pic to compare them
