I think that in this case it's ok to leave those RCA club scans here, since they still have DSX-50135 as the primary cat no. I have added R113453 as an alternate number.
Added label scans { 3461289 - 3461292 } intended for 'stacked' playing, i.e. disc 1 = sides A & D, and disc 2 = sides B & C. One little error is that the side numbers on the labels reflect a non-stacked order: disc 1 = sides 1 & 2, disc 2 = sides 3 & 4.
