This lens is brand-new, mounted onto a Jo Lommen lens board. The removal of the lens and mounting was done by S.K. Grimes. You won't find another like this. The lens was brand-new when I got it - WW2 surplus, stored in a warehouse since 1945. It was still on the K-24 aerial camera, in the original packaging, untouched. I bought the camera intact and had S.K. Grimes remove it from the K-24 and mount it onto the Jo Lommen custom Aero-Ektar board. This will mount directly onto your Speed Graphic and the image circle covers 4x5. It's quite an amazing lens. The aperture works smoothly and there are no marks on the glass. Asking $699.99 plus shipping, which is less than what it my total cost. The buyer can have the rest of the K-24 camera and original packaging for the cost of shipping.
