The Traveler 120 is a simple box camera for 6x9cm images on 120 film, made by Pho-Tak in Chicago, from 1948 and into the 1950s. One version appears to be named Time Traveler 120; however "time" actually labels the instant/time selector tab behind it. On examples with flash sync (labeled "Synchro Flash" around the lens), the selector for 1/50th second or Time is located at the top of the lens board.
A flash synchronized version was sold under the USC brand as the Vagabond 120. An identical camera branded Life Time 120 from "Life Time Mfg. Co. Inc., Chicago, Ill." also exists. (Camera-Wiki.org)
