I inherited a cup from my late grandfather. It has a significant importance in my family as my grandfather used to use it in family gatherings. I would like to learn more about it.
From reading in this website, I understand the toucan mark with the letter W attached to it means it came from Vienna, after 1922. However, I do not know what is the meaning of the other mark on the other side of the "800", that has two letters. It is a bit worn out, but i believe it might be either "MC", "MG" or "MO".
Could anyone share insights regarding this artifact?
