Bob Hancock & (California) Dave Nelson,

Yes....it would be very interesting to see the mechanical makeup of both of these seismometers;
or, how they mechanically/electrically "tick".  The only russian instrument on a search engine I 
found (article, with no pictures) was a electroylte model.  I also get the impression that one or 
both of your russian acquisitions are perhaps portables? Verticals?  Sensor type?

I.E., the CME4111 or CME2123, and the ASMET -1V
