Font change on siglo one box

[Aznyse1]

Hi all 

I just purchased a box of Siglo I from a auction site related to this forum  (can I say name ? ) so it should be reliable and vetted vendor and box seems all ok this is just a matter of over diligence .

when comparing the new box which has a 2019 date code to the box I just finished with a 2014 date code (also from highly reliable vendor )

I noticed fairly large differences in the font of the heat stamps on the outside of the box ,

please see photos attached of them side by side and if anybody knows if they had changed the font over the years please let me know

thanks all 

smaller font is the 2014 btw
