Sorry iff in wrong section insurance valuation questions

Need some advise please
Bought our built 1993 but imported & early Danbury converted bay in 1998
The other month
We had an independent vw specialist look at our bus for an insurance valuation & he supplied on headed paper what he thinks our bay is worth
After a full look round including full underside & him even stating it had never been welded & probably been garaged because of it being a solid original bus
So with photos I sent off to my insurance company a month later they have sent me a value
Before I say what they think it's worth I would like your opinions please
