I’m a bit puzzled by this little 9x19 training round (blank firing round) which was found by my little nephew in the nearby forest, a former training grounds for the Dutch military, and given to me.
The round has probably spent quite some time out there, could be at least 20 years. I know these in brass very well, having shot them in my service Uzi and having a number of these training rounds in my collection as well. Head stamp on this one is DAG 85, so a Dynamit Nobel AG round from 1985.
The case material is somewhat deteriorated due to the time it spent out there, but I can’t seem to identify what it is? It certainly isn’t regular brass and the case is non-magnetic. Tried some delicate cleaning but it rubs off in a brown rust-like color.
