Thinking a little out of the box, the 15th PRS (Heavy) flew F-9s (converted B-17s) and was based at La Marsa around this time.
From this link:

"During Nov, the 15th Photographic Squadron (Heavy), 3d Photographic
Reconnaissance and Mapping Group, transfers from La Marsa, Tunisia to
Grottaglie, Italy with B-17, B-25 and F-5."
The 15th PRS was part of the the 3rd PRG.
In a master's thesis written about Photo Recon in the Med and discussing operations during 1943 there is this statement.
" Aside from the other problems faced, the 3d Group required unique supplies and equipment not readily available from local sources. The demand for supplies became so great the group enlisted at least two B-17s from the 15th Photo Mapping Squadron for the sole purpose of resupply. The aircraft made weekly runs to England to obtain the needed materials, especially print paper, to continue operations. " I think the 15th Photo Mapping Squadron is another name for the 15th Photographic Squadron (Heavy).
It does not appear that any of the B-17s identified so far were in the 15th PRS, so perhaps that "connection" is not correct but I thought I would put this out for consideration.
