Yeah, it's the rewind knob, not the asa/iso selector. I've tried pulling the knob itself & just the handle.

Sounds like I'll need repair. Time to stop buying ebay cameras I guess. Bought an FA & FE, both supposedly in good working condition. Both in need of repair without getting one roll out of either. At least the $2.50 Ricoh FF3-AF I found at Goodwill ran a roll through & rewound nice and smooth.
