It depends on the nature of the inaccuracy.

Equalisation problems can be solved quite easily. Nowadays, many clicks
and some crackle can be removed digitally. 

Intermodulation distortion would be very hard to correct. Resonances are
hard, as they vary with level.

Bad microphone placement, especially close micing, would be very hard to
correct unless multi-track tapes exist with the outputs from each mic
kept separate. (Which is not usual in the 1950s).

You can't correct a problem until you have analysed it, identified it
and studied it. Recordings have many different and independent faults.
