As you note, the singular use of CAINO without other markings suggests more likely the place rather than individual maker.
I cannot help but wonder if perhaps Solingen used the 'CAINO' marking in the sense of 'brand' in the manner of 'SAHAGUM', ' ANDREA FERARA'.
I am not familiar with Solingen's use of Italian names(other than obviously Andrea Ferara as noted), marks on blades in this manner, as they profoundly did with Spain and Toledo, but it seems quite possible.
Would very much like to hear more on that possibility or examples of Caino blades known to be of German origin.
