Not sure that the guitar in question was worth a lot--the pre-1900 Martin parlor guitars seem to be offered for between 3k and 10k on eBay, though they don't seem to sell very well.

That's in the range of what a new one might cost-a couple of the articles say that there were 6 props made up--it seems to me that if Martin made replicas, those each would have probably cost the same as the vintage that was broken--

I do feel pain for the lost guitar, no matter what it was worth.
