There are some 10X series rocks that were used in one of the frequency calibrators (No 10 I think) They will need chasing up a little with some "scouring powder". I think that is probably the best bet.....good luck finding one...... I have one but its part of my crystal collection so not for sale :-)) I have seen 453.xx kHz crystals in HC6/U but never come across any 500kHz. You could always put a 500kHz ceramic resonator inside an HC6/U case !!
