Special Air Service (SAS) beret belonging to Lieutenant-Colonel Ronald Grierson, 1970s (c)

Grierson was a Jewish refugee from Germany whose family fled Nazism. After serving with the Army Pioneers Corps, digging drains in the West Country, he secured a transfer into the Black Watch. He then went on to serve with the SAS in France, Germany and Norway. In 1945 he was wounded and captured. On his release, he worked with the Control Commission in Germany as a liaison officer.

This beret is a modern version of the SAS beret, which he probably wore during veteran parades and reunions.
