Lost Gray Black Diamond C4 0.4 Joshua Tree on Western Saga 5.9

I was climbing with two great guys from NY and this cam got pushed in too far into the wall to get out. Please, will someone be so kind as to collect it if they go up and call me at 310-435-9366 so I can get it back to them. The climb is in Real Hidden Valley on the east face of The Sentinel. The piece is before the crux. Thank you. It's actually a great climb.
