But the "CAL" and "Made Italy" markings are in dark black letters.
Seriously, I already showed you, Joseph inverted the image. He linked to the original WC image in his article and it's clear that he used an artificially enhanced negative misrepresentation.

And as Mark Ulrik has rightfully suggested the specular highlighting has obliterated this lettering.
If you want to convince us that the lighting would have no effect then replicate the original photo but until then the ridiculous theory that "they" found a Carcano then swapped this Carcano for another Carcano and then swapped the substituted Carcano for the original Carcano which is now in the archives must be a stretch even for you.
