The VM would be a 15.75 diagonal measurement.  250/15.75=15.87
magnification.  15.87 x 15.75=250mm.  (redundant math again)

At 12x viewer magnification the apparent diagonal size would be 189.
This is a tad larger than a Realist image in the Realist viewer (44mm
f.l. lenses).  I have some 13X VM lenses that I am working with now and
it proves out, the image is slightly larger than a standard Realist
image in a Realist viewer.

The problem with this 13X magnification in VM format?  Too much
magnification for mass produced reels.  They aren't sharp enough.  But
Personal Camera reels look great!
