Unfortunately, there are a lot of worm trails at the top of this folio and they so often look like letter shapes. It's hard to distinguish the ink from the tiny chewed parts (and from the tanning-process scumble).
If that is "h" (it looks like one), it's a calligraphic "h", someone who knows how to hold the pen properly, not the same handwriting as the main text or the marginalia. I wonder if there was a heading on the parchment before the VMS text was added that was removed so the sheet could be used.
