For those countries that did not adopt the other prefixing but stuck with SAPCOR for most LPs, we have...
1962-1966 = SAPCOR 26
1967-1970 = SAPCOR 27
Red Rose Speedway = SAPCOR 28
Material World = SAPCOR 29
Mind Games = SAPCOR 30
Ringo = SAPCOR 31
Band on the Run = SAPCOR 32
Ass = SAPCOR 33
Walls and Bridges = SAPCOR 34
Goodnight Vienna = SAPCOR 35
Dark Horse = SAPCOR 37
Yellow Submarine = SAPCOR 39
Rock 'n' Roll = SAPCOR 40
Extra Texture = SAPCOR 41
Shaved Fish = SAPCOR 42
Blast from Your Past = SAPCOR 43
Many of these numbers were used in Venezuela, but where the UK used SAPCOR, apparently Venezuela used the British number. The Dominican Republic, where they released albums, appear to have followed this numbering as well.
Like most of the pics from An6y66 these images are take from the only worldwide Apple Records pictured discography web-site www.applerecords.nl without permission and not given any credit.
I can't imagine any correspondence with the UK. Even if they had used Sapcor on Beatles and solo Beatles albums, Yellow Sub was too early to be number 39, and the red album too late to be number 26. (Apple had issued about 40 albums by then.) As this Yellow Sub is numbered later than the red album, I agree this is probably a re-issue, not from 1969.
...Just noticed - all three of these Apple albums carry the number R. I. 13856 on the labels, so that's probably not a catalogue number. Not sure what it means though.
Yeah I was trying to work out if it corresponded with the UK codes but it obviously doesn't
I wonder if this is much later than the original uk release then as the Uk apple discography shows SAPCOR numbers in the 20's as being 1970's albums
the only other on I can confirm is Sapcor 26 was the domican rep. release of the red album haven't found any other releases yet
