Dear Ian,

       I think that you will find the AS2 if you root around in the first 
reference.

       http://www.earth.uni.edu/seismograph.doc

       Otherwise try :-AS-2 Seismometer (The Amateur Seismologist, 2155 
Verdugo Blvd., #528, Montrose, CA 91020; $400 with 24 page manual and Quake 
software to connect to PC, see review in Earth magazine, p. 66, December, 
1995).

       Or check on the society which produced the drawings. Can't remember 
the name. 

       Regards,

       Chris Chapman

a PC crash I have lost a number of files. 

The most urgent is the detail drawing of the boom for the Lehman AS2 horiz. 

seismometer, drawing #1004. Also looking for detail drawing of damping vane 

drawing #1009. Any URL's would be appreciated.
