It's the 1972 catalogue number, and 1972 originals were on the orange RCA Victor label, so this is most probably a late 70's repress (not a reissue if it was still in catalogue - it's Discogs-think to call later pressings of the same catalogue number reissues). It was later reissued on RCA International INTS 5061 (1981?) and NL 83806 (1984). So, keep this as 1972 for the first occurrence of the catalogue number, and anyone who has an orange label original can add it here, and get a mod to change the main label to RCA Victor, with RCA as alternate label.
I am not sure if this is a 1972 release on RCA (not RCA Victor) or a later re-issue. If anyone has more information to confirm the year of issue please raise a correction.
No idea about sequence, but... I have added cover scans.
