I have a turner reich 15-24-36, which i think is also called the 11x14 lense
The 36" group is the one I've used so far, and it's seems to be only about a 32.5" focal length, as I've found from measuring it to fit my #16 cirkut camera. I've gotten sharp images from it on that, which may not compare to a regular camera. I bet zeiss had some big old convertibles though. They had just about everything.
