Joselyn,
I own a Camac Atlantide Prestige concert grand, and the full transport cover set, plus the dust cover. The dust cover is quite elegant, deep red velvet, and my “Angelica” looks wonderful in it, like a beautiful ballroom dress, ha, ha!
However, the curve of the neck of a Camac is a little different than the curve of a Salvi. Camac shoulder ends are a bit lower, and the strings in the treble section fan out at the soundboard ends, to make playing up there more comfortable. So, it would depend on how well the cover fits on your Minerva, whether it would look “tailored” or misshapen on a Salvi. If you ordered the Camac dust cover, tried it on your Minerva, could you send it back if you didn’t like it?
Wish I could be of more help, but I don’t own a Salvi or know anyone here who could let me try my cover on one.
Harp Hugs,
Balfour
