Hi, Interestingly, the only matching NA initials among many Vienna silvermiths is Nachmann Agurtin, active 1892-1916. Have seen his mark NA within a rectangle with notches, but also without notches. Regards
Thanks again Krisztián. Yes NA and VN are really similar letters upside down Hehe. I have a lot more hallmarks that I could't find but I feel really dumb but as I said in previous topic I didn't find any good books about hallmarking.
