EV window and 100mm (44mm in 35 equiv.) lens

Converted to accept and use 120 film.

Added thumbscrew for winding,

620 spool for take-up, ground

area for film travel, made retainers

for 120 spool for Kodak 35mm

film caps, cut to fit and route film,

and added light seal material

in critical areas. 28 half turns to

advance film to first frame, then

around 4 1/4 half turns between frames.

Should yield around eight 6x8cm

images per 120 roll.
