It is Desmond Titterington. The first picture is a crop from a shot of the entire Mercedes team at the 1955 Targa Florio, from the book ROAD RACE by Chris Jones; the book was also my source for the photo of Caballo ll in my previous puzzzle.
The subsequent photos are from
www.f1rejects.com/drivers/titterington/biography.htmlI first heard of Titterington in Jones' book; and info on him was rather sketchy...he was a brilliant Irish driver whose career faded into obscurity just a year after the picture was taken.

He also has one of those faces that, to me, at least; seems to look different from different angles. here are a couple of photos that might illustrate just what I mean...
