Hi Guys,
Thank you for reading this. I bought an pentacon six tl and it had some issuses. I fixed some of them.(shutter speeds stuck) gab between shutter blinds. There is only one thing I can't fix right now. If I put film in that camera and try to advance it, it doesnt lock the film spool after advancing. So it goes right back, when I release the lever.
I attached a short video, where you can see the gear that is attached to the spool going backwards again.
I would love to fix that camera with your help, it should be very simple, just something very little that I keep on overlooking.
I would really appreciate your help.
