1941 Form Lower (Upper?) V alpha

Point to a face to see the name.
Please get in touch if you can identify the form.

NOTE:
This photograph came to me from two different sources, namely Ric Sterns, who identified the class as Form Lower V alpha of 1941, and Bill & Betty Warburton, who identified it as Form Upper V alpha of the same year and supplied all the names.
Please contact me if you can shed any definitive light.
