 The present seismograph at Science Museum is of the same general layout and
 so must be a later model of the Milne-Shaw design. The main differences as
I
 remember were: Only a approx. a quarter of the amount weights are now being
 used, the paper was the full width of the drum, stylus design as previously
 noted, the boom seemed to be a bit longer - can't be sure and definitely no
 descriptive card. Other than that it was generally the same and beautifully
 made in brass. I can see from your photo that the mechanism at the end of
 the boom would certainly magnify any movement.
 Also I can't say whether or not it had the same heavy cast iron base.

 Thanks greatly for photo it certainly scanned well.
