Does anyone have any information on a Goerz 10" f4.5 S-Dagor? The lens is in barrel, coated, very large (significantly larger than a 240mm f3.5 Xenar), looks to be a 6/2 design, serial no. is 82xxxx, aperture runs from f4.5 to f32 and has an odd long (perhaps focusing?) thread. It may have been an aerial lens, but I can't be sure.

Any information (even educated guesses) is much appreciated.
