Greetings. I can usually figure this kind of stuff out through an internet search, but I'm drawing a blank for this lens so I thought I'd seek help from the collective knowledge of the forum members. I know that Hyatt was an outfit in St. Louis, MO in the late 19th and early 20th century that sold re-branded lenses from some of the major lens manufacturers. I've attached a couple of images below. Would anyone be able to shed some light on what type of lens this might be, and its approximate vintage? It's in remarkably good condition, with a functioning studio shutter. Thanks in advance. Carlo
