Hello, I’ve recently been gifted a Bell & Howell 70DL, my first 16mm camera. It came for free from a private collection someone was getting rid of and I couldn’t let it be discarded. As far as I know this person bought the camera for looks and not to use, I plan to change that. The issue with the camera is that when I go to wined the camera, there is no resistance or tension on the turn key, and no ratcheting sound of the drive spring being put under load. In my opinion I believe the Drive spring to be broken or to have disconnected from the turn key. I have recently been trying my hand at repairing vintage lenses and 8mm cameras from my own personal collection as a hobby with a great deal of success (surprising myself in the process). I’m looking for any advice to aid me with this repair. Every little tip helps. I know the risks of attempting to replace a Drive spring which is why I was hoping to reach out to someone with more experience and guidance. All the best Chase
