Chris Martin brought these magazines to my attention recently.  The six pointed start with Yiddish inspectors markings are Israeli.  A lot of World War II surplus arms were shipped to Israel after the war, including Thompsons.  These markings have been seen on both 20 and 30 round magazines.  Some of the magazines have been recoated with a heavy enamel paint like coating.
