Silver border CV - orignal?

Thanks for these notes on the 41 serial numbers CY-CL!!

Despite the 41 very likely being the most thoroughly documented calculator in history, I still learn lots of new stuff about it here, like these s/n notes.

Also I've seen very few of the embossed label units; does anyone know why/when/where this was used for 41 production? I was once told this was a 3rd-party after-market item that was sold, but never confirmed.
