I wasn't present at TI during that time, but I did just finish working in the National Archives going over the records of the TI Naval base from 1954-55! I came across a lot of really interesting stuff for a book I am about to complete on the history of the island. Were you present on the island for the 1955 armed services day? I found a large collection of photos from that event on the island, as well as some from a naval officers retirment ceremony on June 28th, 1955.
