Jim --

I have a similar 6 x 13 Heidoscop that has a 12 exposure holder, but it
is for glass plates, not film.  In order to use it, I had to cut some
copper-clad composition board, which was 1/32" thick, slightly thinner
than the thickness of a glass plate, into 12ea 6 x 13 cm pieces, which I
inserted into each of the plate holders with the smooth copper clad
surface uppermost.  Then, in a darkroom, I cut 12 pieces of B & W sheet
film to 6 x 13 cm on a jigged cutter, and slid each piece into a plate
holder OVER the copper-surfaced insert, which managed to hold the film
flat in the holder.  I then exposed the film and processed the sheets in
a Yankee "Agitank" adjustable sheet film developing tank.  

I did this over twenty years ago, and the man who supplied the
copper-clad material has long since died, so I'm sorry, but I can't tell
you where to get such material; I think it was probably used for making
etched circuit boards and may be available at electronic supply stores. 
The copper cladding may not be necessary, but it made a smooth, hard
surface over which the film would slide easily for insertion and removal
in the dark.

There was a 120 roll film holder made for the 6 x 13 Heidoscop, but it
is an extremely rare collector's item and expensive if you find one.
I've been looking for one off and on for a reasonable price for years,
but without success.  The Rolleidoscop was built for roll film use, but
I think the pictures were the smaller format -- those of you out there
on the P3d listserv who know, please correct me on this if I'm wrong.

Please let me know if this doesn't answer your questions.
