Family treasure returned after 3 generations

It completely amazed me when I got this mechanical pencil and pen set. The History behind this gem is that my great grandmother parents bought this stationary set for both my grandmother and her sister. When they were in Stockholm Sweden. They were coming to the United States. My great grandmother about the 1950s was having her house cleaned by her neighbors when my grandmother didn't have enough money to pay them she gave them this pen and pencil set. There daughter who new me since I was a girl came to me a few weeks ago and gave me the pen and pencil set. I was shocked and excited it is a piece of my family. I have tried to research were this pen and pencil set came from and what is there history. I have been doing research but have not found a pen and pencil set on the internet like this. It is silver with gold plate. Has some gems in the pen and pencil. The pencil still has led in it. I would like to know more if anyone has information it would be greatly helpful. I just want to know the history.
