I am guessing the diamond emblem on NOS boxes/parts is older. Any ideas on time frame or when they switched?

I know the gear in the diamond had been around since 1901, and around 1967(IIRR) they went to the triangle AC, but remain clueless about the micrometer logo...

Diamond with Allis-Chalmers under the A-C is 1949-1965. Triangle is after 1965 to the end. Diamond with Allis-Chalmers and Milwaukee is pre 1949. Micrometer was used mostly in the 50's ------------- Nothing is impossible if it is properly financed |
