Hi, all -
Last week, I picked up Jim Fitzgerald's 12" brass portrait lens. Tried it out today. Beautiful. I love it. I wanna know more 'bout it.

I took it apart yesterday to clean some haze from the inside of the rear elements. The lens is four elements in two groups - front group cemented, rear group spaced. Petzval formulation. But the lens says "12 IN EQUI", which I'm assuming means 12" equivalent. The elements are about 2-3/16", which gives an aperture of about f/5.5, right? Kinda slow for a Petzval.
Anyone able to tell me anything about this otherwise unlabeled lens?
