Having just upgraded my copy of Audacity I was playing around with it
last night, and I'm sure those curves were high at the LF end and low at
the HF end, which would make them playback compensation rather than
record pre-emphasis.
While you've got audacity open can also use its noise
removal tool to cut out rumble and tape/preamp hiss.

you need to
reverse the RIAA curve to get
back the original signal.
Audacity has a built in 'equalization' effect with presets for several
disc cutting curves, including RIAA. I'm not sure how you would use
it to reverse the curve though - it looks like it was designed to add
vinyl/shellac equalisation to digital recordings, rather than remove
it from analogue ones recorded without a correcting pre-amp.
