Something fell on the church console breaking (off) the choir manual lowest 3 (C, D and E) keys (plastic key caps?). Plastic keys mounted to a metal key frame.
A mystery as there is no evidence of what fell. Only the 3 broken off pieces of the keys on the floor. Actually in between the pedal board. Too much damage to consider gluing.
It is a Fatar DF keyboard. Had to have been quite an impact. No other apparent damage. Any ideas other than replacing the entire keyboard.
