1916 Gen. Pershing 'invasion of Mexico ' 30.06 training blanks? WWII Ship ID case for pilots!

Found these yesterday while at my regular thrift store!

Image search and key word search didn't turn up anything similar on the General Pershing training blanks - could these be real? Or vauluable, like stuff found near civil war battlefields?

It was donated with the WWII model ships case - which I've found was used to teach pilots how to identify friend from foe ships, so they didn't bomb the wrong one(!), so maybe it was from someone who collected military stuff & possibly real?
Thanks for any help!
