Can you photo the other side of the cones? I think they are salvageable. Maybe some other members might come up with the rest of the parts to make it good. If we can, you can send it to me and I'll recondition it for you free of charge and send it back. Inspect the case really well too for cracks, as if it's cracked, all bets are off, but if not, it can be saved, I believe.
