Photos of 3rd CLY Crusader tanks in the Western Desert during WW2

Photographs of the 3rd County of London Yeomanry during their time in North Africa during WW2.
I received these photographs from my Grandfather Ken Medcalfe in the 1970's, along with some of his badges. I inherited his medals and other items when he passed away in 1993. I've scanned the photographs myself and they haven't been digitally enhanced. I believe most of these have not been published before, although I've recently discovered some of the same photographs online at the National Army Museum. These are from an album belonging to Major W.H.J. Sale. I've no information on how my Grandfather came into possession of some of the same prints.
I wanted to share these with others who may be interested and as a tribute to Ken Medcalfe. I've done some of my own research in recent years but would welcome any observations or further knowledge/information regarding anything in the photographs.
