photographs of black nurses from the 1950s/60s in the Cov & Warks area?

I've got some photographs of black nurses who I think are from the 1950s/60s in the Cov & Warks area.
However I've got no detail of the source, dates, locations of the pictures.
I've tried the RCN History of Nursing archives to no avail

I can forward the pics (by jpg attachment) to anyone who things they may be able to help provide some details

Many thanks
