Beagle
Bear in mind there's not a lot of information out there about the project. What the book says is the claw (nicknamed clementine) itself weighed in at about 6 million pounds.
About the only pictures and drawing I can find along with authors from now two books on the subject describe the claw as quite large and designed for grasping the body of the sub. K129 was visited by US spy and research subs in the years leading up to the lift so who knows how and when the bell was plucked from the sea. The interesting part being that the CIA acknowledged portion of the sub would not have included the bell. The book has essentially 3 parts, the sailing and sinking of the sub. The international politics (along with the internal politics of the USSR and the US with regard to the sub) and then project Jennifer. Perhaps the author hasn't it right about spy satellite technology of the day, but the political aspects and the changes occurring from about the time project Jennifer's cover was blown may be the catalyst for many of the unexplained changes of the old guard in the Kremlin and within the Soviet military. Finally, Jennifer itself makes the book worthwhile.
