Hey there!
Here is a well-known photo captioned:
"Major Lonsdale (left), Second-in-Command of the 11th Parachute Battalion and commander of the Lonsdale Force at Arnhem, accepts a light from Lieutenant David Polley, "C" Section (lines), 1st Airborne Divisional Signals, after the battle at Nijmegen on the 26th September. Copyright: IWM BU1131."

I recently purchased a field-made knife owned by David Polley from the photo.
I'd like to get a nice WWII-issued beret badge that he's wearing to display with the knife---
The photo is grainy, but can anyone help ID his beret badge-- It looks like an OX AND BUCKS LIGHT INFANTRY badge to me (ey?)
