In Sharepoint, what is the actual name of the page layout used for the "Article page with with body only" layout option?

I need to swap out the out-of-the-box rich text editor with the Telerik editor for all article page layouts. Unfortunately, I only see three article layouts in Sharepoint Designer. When creating a new article page from within Sharepoint, however, it shows 4 article layouts. The one I see missing in Designer is the one with no option for article images.

Does anyone know where I can find the layout labeled as "Article page with body only"?

The file you are talking about is PageFromDocLayout.aspx.
