Post 1447 (1964)

A very nice slide rule equivalent to a K&E 4053. Made of bamboo by Sun Hemmi of Japan. This example dates to Oct 1964 (date code OJ stamped into the rear, lower, left) and is in excellent condition.

Post 1447 (1931-33)

Another rule built for Post (then known as The Frederick Post Company) by Sun Hemmi. This 4" rule is a rebranded model 30 from before WWII. The Sun Hemmi Catalog Raisonne reveals that "Post 1447" was only used for model 30s between 1931 and 1933. There's a similar but not rebranded model 30 on the Sun Hemmi page.

Post 1446 (1931-1942)

This is the 10" big brother of the little guy above, aka a Sun Hemmi 40.

Post 1441 (1963)

Another tiny 4" rule, aka Sun Hemmi 32, this has a magnifier and a CI scale to go along with the ABCD scales of the above model 1447. This rule bears date code NA, January 1963.
