Vintage Pentel PMG 0.3mm Mechanical Pencil

Great vintage hard to find Pentel mechanical pencil in black, red and silver. Marked on side "0.33mm PMG" and it has a totally faded out silver label below the clip. "2H" is showing in the window. No issues other than faded label, just minor expected wear. Pencil lead goes in and out intermittently, not every time, but I could be doing something wrong.
