Schwinn headset / bottom bracket hardware dates

[olevince]

I know I’ve seen a chart for determining the year of manufacture for Schwinn bearing hardware. There are different symbols for different years engraved into the hardware itself. After searching a bit, I’m coming up empty. If anyone has this info, and you could pass it along it would be appreciated. Thanks in advance for any such help. Regards, Vince
