C1 GENERAL MACHINIST RULER 6" Vintage Rule Miniature No. 300

Description

A friend gave us these items to sell; her father was a Machinist in the USA for a few years. He returned to his home country of Germany several years ago, and his daughter stored them in her garage (not ideal storage). He took excellent care of his tools - some MAY have his name or initials on them.  I am not familiar with all of the proper names of the tools as I am not a machinist, so please view the photos carefully as they are part of the description.
It is in good condition, got some smudges on one end.
