That's the back of one of our naval guns....it is at whitey keevans house, he salvaged that gun back in the 80s. It is thought to be from our wreck "el angel bueneo". One knob has been broken off the cascabell. Our guns had double cascabells. Whitey keevan is involved in the hunt but is in his 90s now. He is famous for finding and salvaging the "el cazador" shipwreck. Many tons of silver reales were salvaged !! Another 2 guns associated with our wreck are located in 2 museums. One is at the atocha museum on the second floor. And the other is displayed at Florida Keys History & Discovery center. There should be 23 more hidden in the sands of time hopefully they will be where were searching. The iron is deep here according to the magnotometer. The pulse 8X sled can look very deep into the sands of time, and we hope to have non ferrous targets down deep !!
