I have a montgomery ward never-fail 3 draw incubator in my cellar. I have the manual also. The photo is a picture of the page that somewhat shows what it looks like (except book shows 2 drawer). The copyright of the book is 1928. This appears to operate from the lamp oil burner. Has anyone ever seen one as such? I've haven't found anything on the internet research wise. Just trying to see if there is any value for this?
