Those are all great reels which I also have. The one with the spike I think is maybe a Kindermann from Germany. I insert the film in the space behind to the spade then bend the film and pull, so the spade pierces the film, then proceed to wind on the reels. The two Nikors clamp the film so you can then wind on the reels. Practice with your practice roll until you get the hang of it. Or, send the ones you don't like to me, I will be forever grateful.
