About 20 years ago I found a (big) box of four of them in the dumpster next to a camera store (somewhere in Queens) that had closed. Two were marked Eastman Anastigmat, and two Kodak Aero-Ektar. There were minor differences between them.
- One Kodak Aero-Ektar had discolored (yellowish orange) elements similar to the "radioactive" Kodak Aero-Ektars, this lens was mounted like yours
- Two of the lenses (one Kodak Aero-Ektar and one Eastman Anastigmat) were mounted in barrels (aluminium I think) with no iris or opening for stops, one of these also had a hood and lens caps that matched the barrel.
- One of the lenses (Eastman Anastigmat) was mounted in a barrel with an iris (marked f3.5-22)
All of these lenses were 13.5" f3.5, and all had the same design: Five elements in three groups, which kind of reminds me of a Zeiss Sonnar. I found reference that it was intended to cover 9x9 film, like the 12" f2.5 Aero-Ektar. I also wrote in my notes that the spacing for the 13.5" and 12" lenses are identical, so (some) 12" Aero-Ektars screw right into the barrel of a 13.5" Eastman Anastigmat.
I ended up keeping the best Eastman Anastigmat elements and the barrel with iris, caps, and hood. I have it mounted on an 8x8" lens board (I don't know if it would fit on anything smaller) but have rarely used it.
Here is a drawing I made of the design, no promises for the accuracy of the measurements. I am not sure why I made it. It will take me a while but I will try to make measurements of the barrel for you and post them here. Feel free to nudge me if I forget or take too long.
