I had a 305mm Aero-Ektar land in my lap. (Not really, or it would have broken me.) This thing is a monster. Must weigh 20#. 13in image circle, designed for 9x9 aerial camera. There is no iris, so it is 'wide-open' all the time. Glass looks good, clear, no fungus or separation. Single coated. 1943. If I could mount the thing, it would break any camera I have. Right now, it is a conversation piece. Are there any practical uses until my U2 spy plane shows up?

Thanks. EW
