From my experience, they would most likely pay out the
claim (perhaps
after disputing it a bit, but then they will probably have scrutinized
it from the get go since it would be such an odd item to insure, and the
value would probably have to be ascertained by an appraiser) and then take
ownership of the original, and then either destroy it or try to recover
some of the expense of the claim by selling it (either for scrap or as a
collectible perhaps).
Precisely my concern, worthless insurance, unless you do it VERY carefully.
What classic collector would be willing to accept the insurance money if
they knew the carrier wonld be scrapping the unit with assurded distruction
etc.
