It is very possible information.
So for example: to which "Staffel" and unit belong Ju52 with code: 8A + LJ (period: 1944/45)
Is it possble that code: 8A was written as small letters and
LJ as bigger code on the side shell of a/c?
Example (for period 1944/45):
8A + LJ and tail rudder: ISL
I wonder if exist orginal photos in Internet/Books of Ju52 from the same unit ?
By the way:
"In Dec'43, Ju52/3m floatplanes were operated with floatplane Staffel of TG4, to which LTSta(See) 1 was later attached. Later LTSta(See) 1 was absorbed into TG 4 and became 17.Staffel. However, as TG 4 was known to have used Roman numerals in the tactical code to indicate the Gruppe, it would seem that even after re-designation, some aircraft of 17./TG 4 may have been attached to I./TG 4."
