HN39,
You think you are looking forwards at the R/H MLG; whereas PJ2 sees himself looking aft at the L/H MLG.
However, the MLG is normally mounted on the rear spar, at the intersection point of a diagonal bracing spar, sometimes referred to as the "Bermuda triangle", so I agree with you that the top-right item is unlikely to be part of an engine pylon.
