Lost fountain pen

I lost a fountain pen that used to belong to my father. It was a gift he received from his students and colleagues at Belas Artes when he was in the hospital almost 10 years ago. Silver colored, Lamy brand, with a visible dent in the cap. Last seen on the Southern side of Houghton Pond, Blue Hills Reservation, Milton, Massachusetts, today November the 1st at 4:50PM Eastern Standard Time (see lower left corner of picture). Half an hour later it was gone. If found, please leave at Reservation Headquarters on the other side of the pond and contact felipe.pait@gmail.com. Thanks!
