THESE ARE VERY RARE. The style is called “Regina,” designed in 1929 by Gerhard Muller for his (exclusive) shop in Amsterdam. They were made for him at Josephinehutte in Germany. The flutes are 10″ tall. See the flutes in the painting by Pieter Claesz (Dutch, 1597/1598-1660). The price includes 5 perfect flutes at $230 each and one damaged at $85. The damaged flute has a clean break that can no doubt be glued using the proper product.
