Authenticity of Grandfather's Joseph Guarnerius Violin

[hakin]

Hello, I have found old violin which belonged to my grandfather. I do not understand instruments and therefore I would like to ask you for help. I have found on the web that there are many copies of these Joseph Guarnerius violins. Could anybody give me any estimate how much this is worth? It is not in a great condition but still playable. Is this non-labelled but old and in good condition bow worth any value? See pics below. Thank you very much in advance.

It's sadly very much like the one on the other thread, but inferior in quality.

It might be worth your posting a better picture of the bow.  A straight on, clear picture of the side of the tip and frog would be helpful.  Odds are it wouldn't be anything special.
