Hi Graham,

If you can pull the crystal a bit (which should be ok with a series C, or a combination of L+C), it's ok.

If you can only operate on exactly 472.5 kHz, potential QSO partners on the continent may have a problem to receive you because there is a permanent carrier on 472.5 kHz, sometimes quite strong in this part of DL.

Depending on the other side's filter bandwidth, a few dozen Hz away from 472.5 kHz to either side will improve things.
