That's definitely the younger brother to my Rauner but its going to need some work! The top varnish has been buggered but the sides and back look like honest wear.
I agree with Paul that something is amiss in bass bar land. I'm willing to bet that its become detached on the lower portion of the top, necessitating removal of the top and a proper repair or replacement.
Bass bar, bridge, dress or replace the fingerboard, replace the missing external linings, sound post, strings, tailpiece, tailpiece wire, repair the top varnish...could be a terrific sounding instrument!
Good hunting!
PS Mine needs a lot of work too!
