Hemmi 34RK Greg's Slide Rules


Hemmi 34RK - Notes

This rule is marked on the front with U.S BLUE CO. 1887 in a very similar way to the Post name which appears on so many other Hemmi rules. I have been unable to determine if this is a reference to the US Blueprint Company which resold Hemmi rules or if it is some sort of promotional item.
