Is this an authentic Joseph Klotz label

[Arithelion]

I am looking to buy a violin and want to know if it’s authentic or not. I’ve attached the label and am not sure.  What else should I look for in this particular violin maker. 
 

Thanks in advance for your help!

we had a real Joseph Klotz (senior) label here

Is the fiddle even plausible? Closest one here would be the last one. You would probably need a hand writing expert, if really done by hand they will all be different by a bit, especially over time. 

I have one with a label very similar to the second one down, definitely old Mwald, but made entirely by Joseph? probably not.
