hi derek
i wasn't able to find exactly what you asked about
but i googled " wollensak victus " and found advertisements and articles.
it seems that the victus shutter was released by wollensak along with the
regno and autex shutters.
it looks like the lens / shutter was from around 1910 +/- a few years.
camera eccentric.com has catalogs from before 1910, and a few years later,
before 1910 wollensak made shutters called "winner", "regular" and "automatic" ( dial on top )
there are also catalogs by 1916 there are more modern shutters
http://cameraeccentric.com/html/info/wollensak_1.html ...
if you look around page 27, you will see the regno and optimo, but no victus ( they do have a victo though )
so it was a shutter they sold for a few years, and changed the name ...
jf standford was a portrait photographer and had a studio in fort scott kansas
he also had a mail order photography business and sold cameras with his name on them ...
i think the name "sunflower jr. " was a camera "kit" standiford sold,
maybe was a cycle camera ( large format clamshell box camera ) ...
your friend should be able to figure out coverage pretty easy ..
project an image of something distant on a wall, or stick it on
an 8x10 camera and see what the circle is ...
my guess is that it is an anastigmatic lens, not a rapid rectalinaer.
your friend might try removing a cell to see if it converts and covers an 8x10 negative.
if you are interested ..
