Did you inherit a long rolled up group photo, perhaps like this?

Coiled up in my collection is this 40 cm long photo of about 130 people, men and women, in military uniform. It has been neglected, the surface is cracked. There’s no indication on it of where, when and by whom it was taken.
A place to start, after you’ve secured the artifact, is to ask AI. Here’s the analysis from Gemini.
Overall Composition and Context
The photograph shows a sizable military unit arranged in a standard formal group portrait style. The unit is meticulously organized by hierarchy, with senior personnel seated in the center, non-commissioned officers (NCOs) flanking them and sitting on the ground, and the remaining enlisted personnel standing in the densely packed rows behind. The condition of the original images shows significant creasing and wear, typical of wartime keepsakes.
Gender Distribution
Male Personnel: Men make up the significant majority of the group. The enlisted men are predominantly wearing standard-issue closed-collar Battle Dress blouses, which served as the standard working and combat uniform for the British Army and other branches during the war.
Female Personnel: A substantial number of women are integrated throughout the photograph. Based on their tailored tunics and distinctive soft caps, they are most likely members of the Auxiliary Territorial Service (ATS) or the Women’s Auxiliary Air Force (WAAF).
Integration: Notably, the women are not segregated into their own isolated section but are interspersed alongside the men in the standing rows. This mixed integration was highly typical of Anti-Aircraft Command units, where ATS women worked the rangefinders and radar while men loaded and fired the guns, or in large administrative and signals headquarters.
Rank and Hierarchy
Commissioned Officers: The senior leadership is located centrally in the seated row on chairs. They are easily distinguishable by their Service Dress tunics featuring open collars with visible shirts and ties underneath. Several are also wearing formal peaked caps rather than standard field headgear.
Non-Commissioned Officers (NCOs): NCOs are identifiable by the white chevrons visible on their upper sleeves. There is a strong presence of Corporals (two chevrons) and Sergeants (three chevrons). They are given positions of minor prominence, seated at the ends of the officer row and making up a large portion of the soldiers sitting cross-legged on the ground in the very front.
Other Ranks: The vast majority of those standing in the rear rows appear to be standard enlisted personnel (Privates, Gunners, or equivalent), lacking any visible sleeve insignia.
Headgear Variations: The majority of the group, both male and female, is wearing the Field Service cap (the folded side cap), traditionally worn tilted slightly to the side.
Buildings
The buildings on the edges of the photograph reveal typical WWII-era military camp architecture, featuring a utilitarian hut on the left and a more permanent-looking masonry building on the right.
The reverse of the photo has about 40 signatures, many unreadable. Other names were too common to be helpful. Checking TNA’s WO 440 series, there were 12 women who matched the signature E Barker.
When I asked Gemini to analyse the signatures, the results were disappointing. Some, clear to me, were misinterpreted. When I suggested my reading to Gemini it agreed. Given AI’s sycophantic tendencies, that doesn’t count for much.
A couple of the signatures match people in WO 440 and were included in compiled Ancestry family trees. I contacted them and soon received replies. Neither were aware that the person, who was not central to their family line, had seen military service. They quickly recognized it was the correct person based on the name and birthdate in WO 440.
I was hoping those I contacted would be able to identify the location and time, which I suspect is RAF Weybourne, Norfolk, later in the war, likely 1944 or 43.
