Very few examples of the 10.5cm are recorded with a colon after the serial number.

Thanks for sharing.

Thanks for your very precise observation.
What could be the meaning of the colon?

 

[NIKON KIU]

The Colon indicates an engraving error or it could mean a duplicate number.
There may be another lens out there with the same serial number.

How can one find out more about this?
