      the right, which locks it in an extended position, permitting the roll of
      film to be placed in pocket. A slight turn to the left allows the spring
      actuated spool center to sprirr.,,- back into place, en[,agin€ the film spool.
     Break the white paper seal on the roll of film, and draw the duplex
     paper across the exposure aperture and thread into slot in the empty
     windin€ spool. A few turns of the winding key will serve to securely
     bind the paper to the empty rvinding spool. The camera back is re-
      placed, Top side up, and the spring catches pressed securely into lock-
      ing position. Turn the winding key to the right until I appears at the
      ruby window, which indicates that the portion of film for the first ex-
     posure is in position. Immediately after each exposure, the next expos-
     ure number should be wound into position at the window. After the
       last exposure-6 or l?-the';vinding key should be turned until
                                                                                                                                                                                                                                                           .      all of the duplex paper is u'cund up o n the exp osed roll of film
