"Hits Of Gold" MONO

[cherbette]

Another mono M&P question:

UK / EMI STATESIDE DUNHILL # SL 5007

LABEL: Black EMI Stateside DUNHILL

BACK COVER: Three-sided Flip Back. In upper right hand corner: “SL 5007 (also available on Stereo No. SSL 5007)”

STAMPERS:
A: (machine stamped, small) SL 5007 A - 1G M 1
B: (machine stamped, small) SL 5007 B - 1G P 1

This is a mono pressing. Fold-down or true mono? To my knowledge, the only compilation featuring true mono mixes is "Farewell To The First Golden Era".
