Crystals for 455 KHz fall in the realm of the unobtainable dream unless you 
have a very thick wallet.

Best bet is to check any buddies that have either military surplus crystals 
like others have mentioned or two-way radio surplus crystals.

Years ago I scrapped out some Masters, Motracs, Micors, and Mocoms that had 
IF filters that used crystals with a 455 KHz offset from the 1st IF 
frequency. Don't remember the exact IF frequencies.
