I have found many old and new anchors during my dives and I should like to research and report them. I tryed to find some information about steel anchors typology on the Net and found few infor about just references of the good book from Paris-Sorbonne University and Mr.Edoardo Riccardi reports wich I coud not access them. If you can help me on this subject please e-mail me Thanks on advance, Francisco Xavier Sousa mop13472@mail.telepac.pt
