Hi Stephen
I love a good project and would happily build your bike up if I got my hands on it. However I am in Calgary Alberta Canada. Last few years I have had to resort to resurrecting 70's and 80"s Japanese bikes due to the lack local to me of any available Laverda projects like yours.
The one truth is that none of these projects make absolutely any financial sense whatsoever........... I do it for the fun of it, better than lounging around watching television, or getting into various sorts of trouble.
assuming your motor/trans is OK, someone taking this on is going to have to throw several thousand dollars at it doing this right, and a huge amount of highly skilled time. When finished, even if I got the bike for free in its present state of disassembly, and didnt ahve to pay shipping etc, the properly finished bike would not command a resale price sufficient to justify doing the rebuild properly, it would still be a money and time loser....... I would still take it on though, makes absolutely no sense........
as to a sale price as is, really boils down to asking roughly total parts values and hope to find someone who would actually put it back together rather than part it out.
