Thanks for the advice

Hopefully this link will work http://tinyurl.com/6jhzuot

I hopefully would just like to have it working, rather than being used
for any recordable readings.

... yes, that link is fine: a wonderful bit of kit! I'd get it up and
running to take readings; bit of a faff to begin with, but once calibrated
etc., it's not too much of a problem: getting hold of the charts is
usually the stumbling block, but George has made some good suggestions as
to sources.

You can of course make your own charts. I know someone who prints off
barograph charts onto photo quality paper using a genuine chart as the
master. The challenge is to maintain the correct dimensions throughout the
process-so that one rotation of the drum is still equal to seven days on the
chart.(or whatever time period the drum is geared to rotate in). I recall
being told, as a student in the early 1970's, that photocopies of large
scale OS maps would be distorted and therefore not acceptable for the
Geology mapping project so I had to buy duplicates of the expensive
originals. (I still have them).
