I do not remember any markings on the old bearings or the bb itself, but to be honest, I also did not specifically look for marking, but nothing major jumped out at me. I will be looking at that in more detail, as I am going to pop the drive side bearing out this week to get a better look it. Everything seem to spin pretty smoothly, did not seem to indicate any issues.
