Hi,
NA AIR 23/1218 does not contain any captured aircraft reports. Rather, it is the correspondence (including the cover letters for the captured aircraft reports) between the Air Ministry A.I.2(g) and the relevant Middle East authority. There is the odd mention of a Werknummer or aircraft code, but that is rare. This file covers 1942.
Two sample pages are attached.
All the best,
Andrew A.
