Mirror stuck in up position on SP500 camera

I found my old SP500 in the bottom of my closet that I haven't seen or used in 20+ years.
I'm selling it so in the process of taking pictures I activated the shutter with the lens off and the viewing mirror popped up and now it stuck in the up position. How do I get it back down??

Most likely your mirror return gear needs lubrication.
While this picture is from a different model (K1000) it is very similar and illustrates where it is:

That would need to be cleaned and put the SMALLEST drop of light oil (like sewing machine oil). Exercise it a few times and it should start responding.
That is one of the most common causes of it but of course it could be something else.
