I think that if you don't have any luck finding a pic of the back head, make up a back head that will fit with the appropriate controls where you think they ought to be. Either you can use it, and no one will know the difference, or as soon as you make one up, a pic will show up forcing you to make a correct one! According to a corollary to Mr Murphy's law, as long as you wait to find a picture, you won't; but as soon as you give up and make something plausible, a picture will show up to highlight your mistakes!
