1920´s Knutsen Harp-steel

Here´s a very hard to find Knutsen harp steel (aka Harp-Hawaiian). Guitar has regular 6 string configuration plus 2 extra sympathetic sets; one 2 string extra bass strings and another 4 string sub-bass string set.
Undefined wood....very nice sound.
It had 2 large cracks that were internally repaired and guitar has been recently restored by a famous Spanish luthier. They are now stable and fixed. Guitar currently plays great and has great sound.
It wears Knutsen Temple Street label in the best condition know for one of these (We have covered it during restoration with transparent plastic sheet to preserve it for the future).
Everyting original; tuners, bridge pins, nut...
