Gravely walk behind identification

Got an old gravely off a friend. Liked around and it looks like a gravely pro 40. I need the starter recoil but can't seem to find parts anywhere. Is the model number wrong or will I have to go to dealer?

Sorry for the link, but it was the only way I could think to quickly upload photos from my mobile.
