Frederick Post model 1462H [1949-1953]  (Same as Hemmi 159)

Some marked "POSTRIG;"  Some carry no model name.  Some marked "Made in Occupied Japan;"  a few (late manufacture) not.  Some also marked "HEMMI 159."

I believe Post asked Hemmi to manufacture this rule to duplicate the scale set on Post wartime model 1462.  (Manufactured for Post by the Roos Company.)
