Could this 1000mm Cyclotar lens have been used to document bomb experiments?
Today’s awesome vintage find on ebay is something for collectors with a taste for rarity and curiosity for military history. You definitely don’t see a 1000mm 40-inch f/8 Cyclotar lens spring up from the depths of ebay everyday! What exactly is this curious-looking item? Well, there’s not much info out there other than what ebay seller brcamera has provided. This rare Cyclotar lens was made by Alan Gordon Enterprises for the US government in the 1950s. It was used at the Nevada Test Site for documenting testing activities (we’re definitely itching to know what kind) from the 1950s to the 1970s. It was especially constructed around a 40-inch Bausch + Lomb f/8 Telestigmat lens and was equipped on a Crown Graphic 4×5.
