1'x1' damper box

It was great to be able to find a replacement for a broken damper box that was installed 22 years ago. As a side note, was there supposed to be a "key" in the box for opening and closing the vanes? There was a small empty plastic bag that looks like might have had one in it. If one was not included, could you give me the information on how I could purchase one.
