Here are the pictures. The color looks weird in the close up pictures, but it is definitely teal, not green. Also, I guess it is a weird J before the C, it just looked weird upside down and sideways when I was under it lol.
It does look like a high shank foot so the one you linked should work. I don't have any other plates or feet or anything, just what it had installed on it already.
As you may have guessed from my lack of knowledge, this is my first and hopefully last sewing machine (I say last because hopefully this will work for me for my whole life
)
