50g - Differences in production batches

[Michael Lopez]

Thanks Bob for stirring-up the "hornet's nest" regarding the Blue version :-) . Our learned "Hornets" always provide amazing information & insights when they get going.

Here are my calculator details to add to the collective data base:

No. Colour Case Serial no. Internal Serial no. Pouch HPK-49 Identifier Manf. Year
1 Black CNA73712453 CNA7387530 "Leather" No 2007
2 Black CNA83100655 Unopened "Leather" No 2008
3 Blue None CNA1352375 "Canvas" No 2011
4 Black CNA23801VF CNA2323649 "Canvas" Yes 2012

My Blue calculator was purchased as a new item from a USA based Ebay seller. When I noticed it didn't have an external serial number sticker, I wondered if some of these calculators were released into unofficial markets without these details, whereas in markets such as Spain & Portugal they were released as official products with all the usual identifiers.

Cheers,

Michael
