In that case we can think that the film was probably properly exposed...
Thing is film ages faster after it's been exposed than before...
On on hand, film acceleration would squeeze the last bit of exposure from the film...
On the other hand, it would make grain worse than it was at the time...
Acceleration is usually recommended for fast films, not the slow films of the days...
I really don't know what to suggest as I don't want to feel responsible for a bad development job...
