Karl Hofner violin

I recently obtained a violin ( in fair condition ) with the following
printed 1" X 3" label inside the body:

Karl Hofner
Bubenreuth 1959 (or maybe 53)

the 59 is handwritten in pencil or perhaps ink.
the label also displays to the right of the words a circle containing 
a cross above the initials KH

the entire label is bordered with what looks like a series of the
letter A resting on a line with curled tips on each side of each
individual letter. since the curled base is adjacent to the center of
the lable, the border bottom looks like a series of the horns of a
ram.

My question is: what kind of instrument do I have? is it worth sending
to a professional for restoration? or if I wish to refinish it myself,
am i going to be ruining a valued violin? Thanks for any assistance
you can provide.

Sincerely,
Sherry
