Seems to me that this is most likely an original, as it still has the original company name of "E.M.I. Records (The Gramophone Company LImited)", which became EMI Records Limited in July 1973. Definitely UK because of that company name, an American issue would refer to Apple Records, Inc. (see the linked US 8-track).
Unsire about the date Greg, but as to the other quieries, it does state on the top right of the front cover that it is an Apple tape, so I'd go with that on that point.
...Secondly, the tape cat being consistent with that on the cover, which, as you say is G & L made, and also states it is a UK made and printed cassette, makes it UK for me.
And finally, the "Made In U.S.A" is impressed in the cassette itself, so I think it is the tape stock only that is US, shipped to Blighty where it was used for this title.
In this was it might be very much like the situation with CDs, where discs, cases,covers and inlays for one title are assembeld from available stock from all over... so if they ran out of satndard cassettes due to demand, they get a few blanks sent over from US to meet it.
If it was something like a contract press, I think that would be signified on it in some fashion.
(Unsure though if that eliminates the possibility of an issue for export though: "Here's a few thousand tapes G & L.... print us a ton of them" type thing).
Firstly,let me apologise for the condition,i found this whilst rummaging through an old box of tapes today and thought it might be worth adding to the site(i'm sure someone will have a tidier copy to replace these images,as usual,feel free to change any/all pics).I don't know a great deal about tapes,so i have a few queries...Is this from 1971?(it doesn't resemble any on Discogs),is this UK?(it has "made in U.S.A." on the actual cassette),and EMI or Apple?(there's no Apple logo).I notice it's printed by Garrod & Lofthouse.
BTW...20,00TH image on this world:)
