Lucia Di Lammermoor Orch. Score?

I don't know about any publications, but many Bottesini manuscripts are now viewable at internetculturale.it. As for this piece, I found a "conductor score" which is really just a piano reduction, but also this set of parts: Multimedia viewer

So if you want to perform this with orchestra, you'll either have to hope that your musicians will be able to read from printed manuscript (and that your conductor is willing to conduct from a piano reduction), or invest the large effort required to typeset a score and parts from the above manuscript parts, or keep looking for an edition.
