We were able to get a bargain on a 22 string celtic harp for my daughter when the music store we rent her cello from aquired one from another, defunct music store.
This sounds very much like a Paki. You could contact mid-east manufacturing (www.mid-east.com), or you could also try the new universal tuning key from Dusty Strings, although they are pretty expensive.
It might be possible that this harp is a Musicmaker harp. You can buy kits and put them together yourself or they can make it for you. One option they have is carved sides. Check out their website and look under “Harps” and “Decorate Your Kit”. http://www.harpkit.com
