The Synchro Flash 120 uses 120 film for a 6x6cm exposures and it is a box-type camera with an all metal body produced by Lifetime Camera Company in 1955. It has a 110mm f5.6 Zellar lens with two shutter speeds of 1/50 of a second and TIME. The camera also has an optical viewfinder, flash contacts behind the shutter selector, round small red window in the back of the camera for viewing the frame number on the backing of the film, and a handy carry strap connected to the viewfinder. It is extremely difficult to change the film in this camera. You have to remove the front of the camera or the whole lens shutter assembly from the body while pulling up the film advance knob. The Lifetime Camera Company was out of Chicago Illinois and the identical camera was also released under the United States Camera Company name as the Vagabond 120. The Pho-Tak Corporation used the body and lens housing to produce the Traveler 120 with no flash and the Scout 120 with female flash sockets on the side of the lens housing. The Traveler 120 Synchro Flash was also produced with both the posts on top and female flash sockets on the side of the lens housing. The Traveler without flash capability was affectionately or mistakenly known as the “Time Traveler 120” because of the labeling for the pull tab (poorly placed) for timed shutter speed. The Pho-tak Corporation was active from approximately 1948 to 1960 and was connected with United States Camera Company plus the Lifetime Camera Company both based in Chicago, Illinois also.
