Did you compensate for bellows draw?

Is the aperture scale on the shutter correct for this lens? It should show values from 5.6 to 64.
Is it a Copal 1 shutter?

That value (6.5" = 165mm) is less than the flange focal length of the lens (174.4mm). How did you measure it? (Diff is only 9.4mm = ~3/8".)
Was your subject at "infinity"?

subject was 44 inches from lens board, and 52 inches from film plane.

That's only about a 26mm extension from the infinity position, which should not require any bellows compensation.
I'm at a loss to explain the problem.
