I recently moved, and I discovered another case hidden in my closet. It's from my father's massive collection of camera gear. I thought I had sold all of it, but there was this case containing a gigantic lens: a Bausch & Lomb Telestigmat, with a 40 inch (!) focal length. It looks quite old, but it's in pretty decent shape and is complete with lens shade, caps and a couple of filters. What vintage is thing? It's mounted on a 6-1/2" square Plaubel lens board with a huge Ilex no. 5 shutter. When were these things made? It's serial number VF9178R. I can't find much info on these things: one string suggested these were used during World War II for aerial photography. This is the only lens that he actually had a nameplate fabricated for, so I figure it must be worth something.
