Whow, looks nice 
Is that camera body for this lens, or only a size indication?
I suppose it has clear (not colored) visible transmission, so I would say it is for the visible spectra.
Iris, but no focusing mechanism.
US manufacturer.
-> Military, probably aerial for the aircrafts at higher heights (like U2)?

USAF bought 'em, so for some aerial application or other. |

Pardon my ignorance, but what does AWAR stand for?
I notice the lens was made in Inglewood, CA, isn't that also where Lockheed had a factory?

Edit: Nevermind. It's in the datasheets you sent me

Ian, I'm surprised at you. Yours is a tiny little lens of nothing at all.
I'm pleased, though, that you understand one of the reasons I'm not strongly in favor of most longer lenses from aerial cameras.
Thinking of which, for those who want such things, there's a 100/5.6 S.F.O.M. (covers 4x5) on offer on leboncoin.fr. Topogon/Metrogon clone, I think. I have one, don't recommend getting the one on the 'coin, but advice from me has rarely stopped people from making foolish mistakes. The lens itself is in a light alloy barrel but the cone is very heavy; my initial reaction to mine was that the Armee de l'Air must have flown battlecruisers. |
