Help with C12 Magazine winder

[Jackssv]

Just got a cheap, cheap winder accessory for the old C12 back. Is there anyone who knows how to attach this thing??? Would greatly appreciate the help.

First, make sure the little screw is screwed out (not entirely, but far enough).

Then lift one half of the wind key (either one, it doesn't matter) far enough (i.e. only a bit) to (next step: )
slide the winder over it.

When done with that, fasten the screw again.

Sweet! Thanks so much. Worked like a charm.
