""Back focus isn't all that helpful
It is when the barrel has been shown alongside a tape measure.
Early listing of focal lengths in adverts often gave the, easier measured, back focus.
14" + 3 1/2" gives the eq. focal length of 17 1/2".
I have an voigtlander portrait objective 7 that look a lot like this one. its my favorite lens ever. Great find.
