hi Larry

the CR series, from CR-1A/U to CR-65/U, is a millitary code for
standardization of crystal holder, in this particular case CR-27/U
stands for


CR-27/U 
case:                                HC-6/U  
frequency range:            800 - 20000 Kc
frequency tollerance:    +/- 0.002 %
temperature range:       +70 +80 °C
resonance:                      parallel
load capacitance:           32pF
mode:                              fundamental 

(from the book "Radio Trasmettitori" italian translation of "Radio
Transmitters" by Laurence Gray Richard Graham    Mac Graw-Hill  ) 

I hope this information is usefull to you .

> I need to order a couple of xtals for my exciter model GPE-1 and also one for an STE-1 and hopefully a future pair of STE-5 units i have spotted taht look pretty nice.  International xtal wants to know what the load capacitance would be.  I suspect it will be 20-30 pf but don't know for sure.  I think JAN also wants that info.  I don't know that they ahve any info on the TMC line of equipment so i need to come up with something.  ANy ideas?
