Diamond started off making bicycle chains in 1892. Two Hoosier bicycle mechanics used a Diamond chain in their first successful heavier than air flying machine, maybe you've heard about it:

The design and layout of the Chain Gang mags are out of sight; informational, inspirational and even beautiful:








It would be my guess that Diamond Chain Company is not a union shop which might explain their continued profitability. Especially poignent are some of the political messages included in the publications, very timely for our age:

Most people, even citizens, arent aware that Indianapolis has a long rich history of auto manufacturing and innovation second only to Detroit. The Indianapolis Motor Speedway was originally built as a test track for makes such as Lexington, Cole, Dusenburg, Marmon and Stutz. The founders of IMS were (L-R) Arthur Newby owner of Diamond Chain and National Car Company, Frank Wheeler of Wheeler-Schebler Carburetor, the legendary Carl Fisher and James Allison founder of Allison Transmission.

I love stumbling across the forgotten pieces of my city's automotive, motorcycle and racing glory. Diamond Chain is yet another living link, no pun intended.
