Richard's answer is entirely right. More specifically, the dome-top safety valve was introduced in 1916, and builder photos of tank cars all through the 1920s show a gradual change from elbow to dome-top valves. By, say, 1930, new cars were no longer receiving elbow valves. But as Richard often and rightly observes, tank cars remained in use for many, many years, and elbow safety valves could readily be found into the 1950s. Certainly there were plenty of them in use during World War II.
