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.
