A few O/N of vessels named Colombo, from my files: 25124, of London; 37096, of Liverpool; 38533, of Sydney, CA; 47664, of London, and later of Hong-Kong; 54994, of Liverpool; 61351, of Miramichi; 62058, of Greenock; 45664, of London; 900473, of Miramichi. And a Columbo, 58080, of Sunderland. I have many more, but no O/N for them, most were early vessels, this list does not include Italian or French vessels by this name. I must add that I have not done a in depth research on these vessels, since for me are only a curiosity, not having any certain relation with Cristopher Columbus's name, as the Italian vessels of this name have. However when I find any data of them, I take a note of it. Alex
