[ARC5] Are 1.415 MHz crystals available?

[Bruce Long via ARC5]

I found two 1.400 MHz crystal filters in Ebay, one BW=2.4kHzIIRC and the other BW = 1.4 kHz
Both fitlers are a little narrow but you  might be able to open up the fitler and widen it or extract the crystals for re-use
i would have no compulsion against shifting the IF freq from 1.415 to 1.400 MHz  Am am sure tracking error can be corrected by re-alignment and the dial calibration error would be too small to be evident on the receiver tuning dial

Partial correction to my previous - only the HFO tracking or calibration 
would be affected.  The antenna and RF would not.
