Sorry for the loss, but I would love to see the pictures!

Damn. I hope the truck driver was okay.

Have you taken a good look at the horn? From what I see in the photo it doesn't really look all that bad (besides all the "carnage" around it). I'm sure that the valveset might be a bit screwed up and that it would need a good cleaning, otherwise it could be a "functionable" tuba (although not a pretty one without dent work and re-finishing).

Well, you could always tell insurance that it was completely destroyed... what would stop you from keeping the remains?

I feel bad for you man, and I hope you have luck finding a replacement, or salvage the old one (though not looking promising). Again my condolences.
