This is the USS Cobia which is on display at the Maritime Museum in Manitowoc, WI. This submarine played an important role in WWII responsible for sinking 13 enemy vessels back in 1944. Taken with the Nikon Df/Zeiss Distagon 28f2.
Found a couple of 100/2 ZE shots in my archives that I really love the colors in. I traded my MMJ CY Planar for this lens which I had been wanting for some time. The jury is still out on if it was worth it.
