the additional cat# letter prepended to the original trailing "T" appears to've been born from a misreading of the cat# on the original lp's b-side, where there is no space set between the cat#, "ILPS 9081T", and the b-side indicator, "B".
yr hmbl srppnt. s'spects it'll never surface whether the misreading occurred in island's offices, or was by the person setting up the type for the new-style labels, nor whether it was considered, even briefly, by whomsoever was responsible that there was clearly a different cat# for the a-side, ILPS 9081TA:
which might so easily've given us ILPS 9081 TA A paired with ILPS 9081 TB B. . .
Added pink rim labels. The catalogue number has acquired an extra letter. The record is in the same sleeve as the first pressing with the integral booklet.
the first edition of this lp certainly has a full-size, bound-in section. but i've not compared it page-for-page with the united artists' release booklet.
(alas, i cannot report as to whether island's 1986 mid-price re-issue is the same in this regard.)
island's lp cat# suffix letter indicated that the lp cost shops more & was recommended to retail at a higher price (39/11 when island's standard lp price was successively 32/6, 35/-, 37/6...) (this deponent knoweth not how - or even whether - island records premium lps' price rose over this period, as yr hmbl srppnt. only bought this lp the once.)
(i recall one of quintessence's lps having a "Q" suffix - ILPS 9110 Q, ''in blissful company'' q.v.; but i'm not sure this "system" succeeded, before it was succeeded by the standard price of lps reaching 39/11.)
