         Dear crystallographers,

    For about 20 years we're happily using our old Syntex P21 
instrument. It works fine and still produces good results. 
    However, we have some problems with monochromator, not 
actually with the graphite crystal, which is quite O.K., but 
with the housing and its mechanical parts, which according to 
our "mechanical people" can no longer be repaired. I'll be very 
much obliged for any information on the possibility of 
purchasing the graphite monochromator for Syntex P21 
diffractometer (most probably used, but in working condition) 
or just its housing, as we'll certainly be able to fix and 
adjust our old graphite crystal.  

    Please, reply to my e-mail: yan@xray.ineos.ac.ru

  Many thanks for your attention.
