I guess that when I answered the request I should have been more exact, and check my files for any additional data. For many years, 17 or more, I have been making a research on any vessel ever named COLOMBO, COLUMBUS, COLON, &c., and I have been checking thousands of books, in different languages, Registers, Newspapers, Lloyd's List, MNL, &c., even reconstructing the voyages of most of the vessels from early 1700's to date. My file of this COLOMBO, did not show where I got my O/N from, now in checking a file on data I transcribed from the Mercantile Navy List (1850-1920), I see that I got this data from the MNL of 1864. Check for the BRIDGET (37096), in the Alphabetical List of British Registered Vessels. Of course I did search for the Bridget, after having obtained knowledge that this COLOMBO was originally built as the BRIDGET. I hope this clear the confusion.
