[50mhz] Looking for CW filter

[N3XX]

Hi to all,
I have acquired a Yaesu FT-650 for use on 6 Mtrs, and looking for the CW 
filter for this transceiver.
The Yaesu 600 hz filter for the 455 khz IF is "XF-455M601-01".
Posting here to see if anyone on the list has one you would be willing to 
part with, or if someone knows of a suitable substitute.
If anyone has one to sell, or information on where one might be available, 
please email direct to n3xx at charter.net .

Tnx & 73,
Tim - N3XX
