Hi Ami, this is a Camac PH38. It has 38 strings, the lowest being an A two and a bit octaves lower than middle C. The highest note is a C.
I owned a Camac PH38 one for many years. Mine was strung with pedal gut. It could also be bought or restrung with nylon. The harp on the picture has white plastic levers. These are rather stiff and not easy to flip while playing. The modern Camac metal levers are much better.
I guess this a harp dating from the nineties, but you could ask for its number (it’s in the inside of the harp) and mail Camac about the year of building.
Frankly, I think the harp is way overprized. I’ve got no idea prices in the US, but in Europe, depending on how well it has aged, this harp would sell from somewhere between 1000 to 1500 euro’s. Yes, also when converted to American dollars that’s less than half the current seller wants for it.
