I think I have a couple of those that I can send you. Once you've made enough posts on this forum to enable private messages on your account (I think the number is 4), you can send me a PM with your mailing address. Meanwhile, I'll check to confirm that I can find them.
If you can find the frequencies you want on ebay, they go for $4 - $7 each. Otherwise, you can get them from websites that charge up to $10 each. That's for used (or NOS) crystals. Special orders from crystal manufacturers can run $35 and up per crystal.
If you're asking about the ones that I think I have, they're yours for the cost of postage. I'll try to find them tomorrow and let you know. I think I have 155.655 and 460.600.
edit: OK, I found them. Send me a PM if you want me to mail them to you.
