22. SPECIAL ACCESSORIES
If you attach the Sears Autowinder to this camera, the
film can be advanced automatically so that you can take
continuous shots (2 frames per second).
* Before attaching the winder, wipe the contact points on
both the camera and the winder with a dry cloth.
[NOTE: Mike B. - An eraser on these contact points as
well as the contacts on the underside of the camera body
can fix problems if the winder does not function due to
poor metal to metal contact.
