Hi i have been researching all afternoon, dont know if ive got very far but here is what i have found so far, maybe im wrong if i am just correct me as im no expert, here goes,its Italian... i have found the star which says.......
special mark for items in stock, used within one year from the acquisition of the new punches. Were used two versions of the punch, similar but of different size, for large works and small works
this mark was used 1934 ... so this would mean its older than 1934 but because it was still in stock when the new italian marking system came in so was marked with this star
http://www.silvercollection.it/italianhallmarks.html so if this box is older could the mark between the other hallmarks that i thought looked like a crown with a star above.. but if you turn the image the other way round could it be this mark

any advice would help as i may be completely wrong
