I was given a Roto Broil 400 a few years ago and have never used it. It was given brand new in the mid 50's to a woman I know and she used it a few times, but apparently not very much.

I have no idea how it works and she no longer has the book that came with it. I have also searched on line for a copy of the instruction book but I have not found anything.

Does anyone know how to use this or where I might get a copy of the instruction book?
