The pitcher is definitely blown and, I'm suspecting, possibly pre-war.
But, yes, identifying similar colours can sometimes help to pin down, or at least point to, countries of origin based on perhaps national trends and inter-factory copying.
I'm veering towards it being quite likely an importer's label - mainly because I've exhausted all the glassworks I know.

I really should go back to the amber part-set and see if my greatly-improved camera and it's super-macro zoom can divine anything from the label residue that my old one could not - if I can remember where the glass is stored!
