I have a set exactly like that and the matching 16mm HS unit -- worth about $5 on today's market, sad to say. The only thing I don't have is the Goose timing unit, which you must have if you want to have a ghost's chance in Hell of catching anything in the few seconds the camera runs on 400 feet of film.
Remember, you have to shoot long-pitch film in these cameras, .3000" from perf to perf rather than the traditional .2994" pitch used in camera original -- that rules out negative films or contact printing the film that runs through the camera; you have to optically print the film.
God, I am a obsolete old fart...
