[Boatanchors] Looking for crystal parameters for Peterson Z-2

[Doug Hensley]

Hello,
Does anyone have any crystal parameters for the Peterson FT-243 Type Z-2crystals?
In reading Andy Moorer's excellent break down of the SP-600 crystal parameters,I realized how little I know about FT-243 crystals.  The radio that my applicationpoints to uses an FT-243 in the 2nd IF to set the frequency for that circuit whichuses two 6BA6's and one 6BA7.  
Hoping someone may have a data sheet on Peterson.
Thanks in advance.
