Flywheel ? for the /6 guys

Okay I'll count the teeth but I'm betting that it is a 122T. It is just over 12" in diameter and if it follows suit beings a 130T is just over 13" and a 143T is just over 14".
I just hate to toss it if it has a use being it's 50 year old virgin US steel. Yup, I said it again.:D
