Slide rules HOME page COLLECTION 10" RULES U.S.A.
Make Manufactured for Post by Sun Hemmi, Japan
Model 1447

1. This is an example of a rule sold under a different brand name with very minor modifications .
2. The rule is virtually identical to the Hemmi 40RK.
3. On the front of the rule the model name is given in red in the top centre and the Post logo is on the slide.
4. The only difference is in the cursor which on this rule is metal framed (plastic on the 40RK). This may be a modification demanded by Post or may simply represent a natural evolution of rule construction with the rules having been made in different years.
