Just the other day, I was given an old Argus (C3 I think) "Brick". What a neat old camera!!! The person that gave it to me got it from his father, who purchased it right after getting off a ship following service in WWII. He said that he never put a roll of film through it and it just sat in the closet! I loaded up a roll of film and found that the winder seemed to crank through the roll rather more quickly than I'm accustomed. A 1/2 turn on the film wind knob, caused the frame counter to advance 10 frames or more!?!? Is the gear ratio on the winder different? Is there an important proceedural step to film loading that caused this? Can someone help a newbee to neat old rangefinders???
