I have aquired a strange little lens, it is called Junior and uses no front element. TBI for control and f-16 to 258. It is mostly brass with an air cylinder on it. I looks like it mounts with 3 screws. Any ideas..Also with it was a 4x5 film holder made of dovetail wood, with wooden handles on the dark slides. Has a cardboard divider between the 2 sides. Russ

Sounds like a doublet lens from an inexpensive, turn of the century plate camera, a la Poco, Wizard and even a Graphic Jr., or a folder. The aperture is in US stops. US16-256 = f16-64
