Hi. I just found my grandmother's vintage rotisserie and got it all cleaned up. It still works, but I have no manual. I don't know how it works or if it's missing important parts. I've spent hours online trying to find help. It is a Nesco Gourmet Rotisserie CAT# N-166A; Nesco Industries, Inc, St. Louis. I can't even find a Nesco based in St. Louis. Any help would be greatly appreciated! Thanks for reading this.
