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

[Doug Hensley]

Hello,
I have been searching for crystal parameters for the Peterson FT-243 Type Z-2crystals.  In detailing the HC-6U, Andy Moorer calls out:
Case: HC-6/UMode: PARALLELParallel capacitance: 40 pfResistance at Resonance: 200-1000 ohms (not critical, as high as is reasonable)Mode: fundamental, 3rd or 4th harmonic from table abovePrecision: 25 ppm (you can get better by paying more)Signal Level: 2-5 volts. 
If you have some general parameters for the FT-243, please QSL.  The radio that my application points to uses an FT-243 in the 2nd IF to set the frequency for that circuit which uses two 6BA6's and one 6BA7.  
A Peterson guide to their crystals might help.
Thanks in advance.
