Donald,
The Illinois Watch Mainspring Chart is showing all 60 Hour models (13, 14, and 15) to take the # 47309 or old # 1759. They’re very common and can be found on online. I have several original steel Illinois in my parts cabinet that can be parted with. If that’s what you’re looking for let me know. Some people prefer the replacement alloy springs instead. I may even have one of those but I’d have to check.

If it is a model 10 then it takes the 47330.
