Jim Polk is the appraiser we have used. He was responsible for our very favorable insurance settlement when our 69 was broadsided and he appraised our 68 Ambassador that allowed us to obtain a "replacement" policy. We highly recommend Jim.
He is Silverpal2 on the forums, he speaks at the Vintage Restoration Rally and is very active in the Airstream community. He is also a vintage car appraiser. Japolk@jps.net cell 805.646.4557
He lives in California but appraises all over the country. Check him out. Paula
