TubeNet

I'm a bass trombone player on the look for a tuba for doubling and I have found a Willson BBb Tuba (modell no. 2945) for sale at a - in my unexperienced opinion - very reasonable price (converted to american currency that is $ 700). All I know is that it's about 30 years old, a non-compensating 3+1 valves tuba.
I would be glad if anybody could give me some info and opinions on this tuba and tell me wether it's worth the money? I have attached a picture

Kind regards
Bertil

Hi Bloke
I was told, that it is a non-compensating tuba.
The bell diamter is 17". The seller supplied me with a picture of the back as well
