Re my post above, the two versions of the T code used by 56, T* and *T, I have a vague memory that one set of codes was used for the 2 stickers, and the other used for single stick airframes.
Jerry, the code blocks may have been originally assigned to a Sqn, but airframes were moved around Sqn's so often that they were eventually all jumbled up. The first 4 airframes in your post above, were probably with 56 when the codes were applied.
Re the J* code for 111 Sqn I mentioned, this was JU on a specially marked F3, which was their code in WWII.
