Somehow the pictures didn’t attach. People will want to see several. Look for a serial number on the action. Count the number of strings. What are the lowest and highest notes?
If you’re looking for information on the condition, it will help to see photos 1) straight across the sound board (to see how much it is bowed), 2) at the bottom of the body/soundboard on the left (D) side where it meets the base, 3) squarely along the neck from the player’s position, 4) straight down from above the neck with all pedals in sharp showing the third octave, and then the general photos that one would take of the harp.
It should be pretty easy to find a technician in the midwest. Where in the midwest are you?
