These are the serial numbers I've dug up over a few months.
"C" means the lens is engraved with a red C indicating coated.
No C means the lens doesn't have the red C engraving (but still coated).
Production is certainly very low. Perhaps as low as 1,200 - 1,500 lenses.
Has anyone got any other serial numbers to add?
