Kufo shaper

I have a friend who gave me a kufo shaper SK-28sp. It has a 1” spindle with a thread pitch of about #12. As far as I can tell. It is an earlier model that has a fixed position for the spindle. I’m missing the spindle nut, throat plate and would love to find a service or owners manual for. Any help getting more information would be great. It was rusted up pretty bad but after many hours of painstaking work I brought her back to life. Just need a few more things. Thanks
