E. I.
HC-110 Condenser B 5:30 m 68° F 100
HC-110 Diffusion B 6:30 m 68° F 100
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.

Additional Comments:

Georg Kern:  The main distributor for Efke films in Europe is Fotoimpex in Berlin/Germany. Go to their homepage at http://www.fotoimpex.de and klick onto  the developer tank on the lower left corner of the opening page. This will  give you time tables for (Croatian) Efke and (Czech) Foma films with many  different developers. The list is in German and English. Fotoimpex ships  worldwide, I think.
