I recently used a Praktica Nova I for the first time, took all 36 pictures and realized that I loaded the film incorrectly. As you can see from the manual screenshots, one is supposed to insert the film into the take-up spool (22). Instead, I inserted the film to the transport sprocket (21).
When I tried to unload the film I could not rewind it using the rewind knob (3). I also tried to manually help it in the dark room which was not successful. It feels like the film is wound around the transport sprocket (21). I cannot move it in any direction.
Looking at the manual I wonder if unscrewing the supporting piece (23) allows me to take out the transport sprocket (21) with the film?!
I want to try to save the film from being destroyed. The last resort is to open the camera in daylight and cut the film off the transport sprocket (21).
