Help with 50G serial numbers

[100LL]

The 50G doesn’t seem to conform to the post ‘96 decoder offered here: https://www.hpmuseum.org/collect.htm#numbers

I’ve searched the forums thoroughly and can’t find further guidance.

Seeking help in turning 50G serial numbers into manufacture date.

Thanks

And as a bonus, 49G+ decoding would be nice.

For my 50g's

CNA62800xx
CNA70100xx

CNA - Manufacturing Facility
6 - 2016
28 - 28th week of 2016
00xx - number within batch.

CNA - Manufacturing Facility
7 - 2017
01 - 1st week of 2017
00xx - number within batch.

the 2016 unit was purchased as a full package.
the 2017 unit was purchased as a refurb - or more likely, leftover new.

Seems like a single digit for the year might be insufficient for the model. Didn't have a run longer than 10 years?

Intro in 2006, disco in 2015, so no problem here.

The 12C, and 41C family, plus the 17BII+ (Silver) are likely the only HP models with > 10 year manufacturing history. In the first 2 cases, there are other indicators to know which end of the mfg. cycle a unit is from, such as country/factory of manufacture, design changes (think halfnut, more/different batteries), stamps/markings on the device, etc. so it is not likely to become a problem. The 17BII+ is less clear (I have not seen recent production units, but production still continues) but I'd guess the country/factory codes differ for this model as well.

Even if the Prime makes it to 2023, it still should be easy to discern, as recent models include notation (e.g. "G2") on the device to clarify.
