Some of you have a Vivitar Wide and slim, and most of you know it's bad history of having the wind on mechanism break. Especially if you use a 36 exposure roll.
Seems the little plastic bits inside are a bit weak, so it's recommended to use 24 exposure rolls to avoid this.
However, if it does break...
Don't toss it, fix it.
You can do so by drilling a hole in the top of the camera just behind the "Vivitar" badge.
Put a winder in, (in my case a stick) and carry on. I had a nicer winder at one time, but lost it, and currently use this little stick.
A trimmed Popsicle stick works fine too, or a small dowel.
