At first I thought that the L maybe was "A" as in "Rewind"
and "Advance"... but a look at Prof. Werner Weiser's excellent
reference "Stereo Cameras since 1930" clearly shows the "R"
and "L" settings at the top of the Stereo Graphic.  My 
guess would be "Load".  Put in L to load the film and go on.
When done, switch to R to rewind.

Another "tip" about this camera.... Since shutter speed is fixed
at 1/50 and the smallest aperture is f16 you should use ASA 50 film 
(or Kodachrome 64), otherwise you would not be able to get good 
exposures in a sunny day (remember, "sunny 16 rule" : 1/ASA @ f16)

Also, the camera has fixed focus with each lens set at a different
distance so at least one half stereo picture is sharp.  At f16
you should not be able to see a difference but you should at f4.
