TJ.1 sailed on December 16, 1942 from Trinidad to Recife. In July 1943, the series was restarted, again at TJ.1, but sailing from Trinidad to Rio de Janeiro, ending in February, 1945. For some reason, the series jumped from TJ.65 to TJ.216. There were two additional convoys in March, 1945; TJ. 219 and TJ.220 from Trinidad to Recife and Natal, Brazil respectively.
Note that convoys TJ.66 - TJ.215 did not exist.
