Comments:  I recommend EI 100 followed by small hand tank processing.  Agitation with these short times is for the first 30 s and then the first 5 s of each following 30 s.

Comments:  KB stands for “kleinbild” [small picture] and R for “rollfilm” [i.e., 120].  There is also Efke sheet film PL100.  "PL" stands for the German "planfilm".  Agitation for 5 seconds every half-minute.
