French Silver Flatware

My mother and I found some old Silver silverware that was packed away. I found markings on the inside of the spoons and forks marked 84 on the left and SOH on the right. Upon searching for hours on the internet I cannot find the makers mark anywhere. These pieces are from France and have been handed down to me. I don't know what year these were made and I am very curious about them. I apologize for the photo. It isn't the best with my camera.

Good
