I decided to use the forum for this issue because it concerns several editors:
Swindon was productive since 1986 and all earlier UK releases were made in Japan or Germany (maybe not all). On MB we have The Wall (made in the UK, printed in England), released in 1986.
But that’s not what images and the Discogs relationship ( Pink Floyd – The Wall (CD) - Discogs ) say: “unknown” release date with discs very likely not manufactured in 1986.
The first release made in the UK was probably this release: Pink Floyd – The Wall (1987, CD) - Discogs
I don’t know if it was in 1986 or 1987, but it has earlier discs and no barcode on the back. There’s also this version, a possible duplicate, printed by “EMI Services Benelux B.V.”, but that’s not shown on images (→Printed in England).
There is another Discogs version without barcode, containing discs manufactured in Swindon (earliest known version 2) and printed in Uden. They could have been released in 1986, though more likely 1987. (on MB is a similar version with barcode, released in 1987 - that’s possible)
Now, there should be a 1986 release, if there was such a release date, but the currently documented release is definitely not from 1986 - what should be done?
I hope for the help of @IvanDobsky, but also like to invite others who contributed recently @Zas, @kellnerd, @Goose90053
Another problem: should additional information really be entered into the cat# field?
→ “CDP 7 46036 2 (cd 1), CDP 7 46037 2 (cd 2), CDS 7 46036 8 (case)”?
And the same line seen for made in the UK, printed in Holland has misspelt cat#s for the discs. It’s no surprise, it’s not easily legible.
(the additional cat#s on the discs are no distinguishing feature and appear on all discs from similar releases)
