Hard to tell but likely a "51" aerometric.

I don't see a blind cap and the clip indicates a "51" Aerometric, 1948-1969 timeframe.

I'd say a P-51aero from 1948 until about 1960, or whenever they began using the same clip as on the Parker 61. Also note the rounded, rather than flat or pointed, blind-cap end. The box is roughly that period, also.

Of course, cap and box can be from other pens.
