Atelier du Tabalou is the studio name !! I am assuming they were the designer of this piece and did the artwork !! I looked at several pieces from the same studio but they were more ornate that your vase !! Can I ask the size of the vase ?? Sizes , marks, ect are important in determining value !! Will also help if we have pics of entire object, front and back !! Like the knife,,we need it out of the case if it has one, lay them side by side and then turn over and do the same. then close ups of details like the handle with swastika !!
