Dreaded WIW? Please advise

[5window]

The attached photos are of a car that belongs to the "friend of a friend". Really. The owner died, leaving no will, but three kids who will likely end up in a legal dispute over the estate.

They have a certified appraiser lined up if need be, but it would be really great if I could help them ascertain an approximate value. All I know is that it's a '31 and it runs, but hasn't in a while. The car is in central PA if geographic location affects the value.

Thanks to all
