I have played a bowed psaltery for some 30 years or so and I have yet to play a nicer one. It was made by Hopf, a German firm. I think you can still buy them; they are very solidly made. I ran over mine in a mini van with no ill effects! The Early Music Shop in Bradford, who have recently resited to Salt's Mill down the road in Shipley, sell them. If you are too far away they do an approval system by post.
Hope this helps.
