violin

I have this violin that is in its original case.  My grandmother used it for her lessons when she was a child, and she had received it from her mother and i think so on.  On the inside it has a little label that says czechoslavakia antionisu stradurius.  Ive  looked online for what i may be and i would like to know the value, i also have within the original box is the bow, which is a little rough, and a sholder rest, and an old rosin.  which is labeled made in france, palmetto aug. grouses.  special process rosin.  and the label inside the case reads origanl G&B improved.  Thank you. I really woul dlike to get some information on it, it is just sittin in my house.
