35s — CNA721: 2007 or 2017?

[cdmackay]

thanks very much both.

Indeed, you are right: I belatedly asked the seller, who confirmed he bought it in 2007, and then hardly used it. Nice to get such an early one in nice condition.

But presumably 2017 ones would also have a serial starting CNA7? Or did they switch to a longer format (like happened with the 50g) so you can tell the difference?
