I have some original red external chainring bolts fom the STS Lobo I sold years ago that are Laser Etched with "AC Made in USA" in white. You'd be welcome to have them if you want. One of them is a bit faded as it was the one that is hidden on the inside. They are not mint but they look good and are an original detail.
If interested I'll try and post a pic. I also have the original AC 46T chainring if anyone is after one (110BCD 5 bolt).
