Puggo's Swedish 16mm preservation, which is cropped at the top instead of the bottom, only have one cue mark.
Well spotted! I suppose they had to crop the top to preserve the burnt-in subs at the bottom. Otherwise it seems common practice to preserve the top of the frame when cropping for 8mm/16mm anamorphic.
This would also indicate that the subs were burnt-in (literally, as they were on film back in the day) on the source of the 16mm reduction, not afterwards.
