Eb flute

I have an old Eb 8 keyed German flute (era 1930 I am informed) which from memory is in good playable condition. It has been rarely used for the many years that I have had it due to much of my recent life travelling in other lands and also I rarely get a chance to play with other people. I should like to have some idea of it’s value before I consider parting with it. I travel with my old German 8 keyed D flute which is a fine instrument and can take a bit of rough treatment. I cannot supply photos as the flute is at present in storage until my returrn from China in late January…Any offers will be considered.. Jerry
