Dan,
I think Dale A's was suggested by one of the users, he has vast Tiger experience and is held in very high regard for his restorations. There are several other Tiger specialists, but not sure how close they are to you.
A good thing to do would be to join CAT and make it down to a meeting, there will be some guys there that can look over the car for you and probably advise you as to any issues that might be obvious, also point you in the right direction for assistance.
The car looks to be a very honest example, i'm sure it will be a matter of some servicing and then regular use to keep it running well. If the car has seen limited use a few issues might be:
Stale fuel or varnish in the tanks, also flaking of the fuel tank paint in the fuel lines.
brake hoses on the front have a habbit of going soft on the inside and causing the brakes to stick on or pull to one side.
Rear wheel cylinders can leak if the car has sat for a long time.
Overall the cars apretty tough and a good drive is often all thats needed to get things loosened again.
