I have a device which I am told records temperature rather than pressure? but looks very like a barograph. It does have what looks like a bi metalic strip protruding from the back end.
On the plate is 'L Casella London agent for Ricgard Feres'. The only number looks like a batch number 32331?

Hi Martyn, thanks for your enquiry. The object you have may be a thermograph. You can make a visual comparison here: http://museumvictoria.com.au/collections/search?q=thermograph. It was not manufactured for Richard Freres, but was used by the Melbourne Observatory.

I have an identical and fully functional barograph with serial number 22740. It has however no inscriptions or plates beside tha serial number.

In addition I have a small box of paper sheets for registration of air pressures to be mounted onto the cylinder. They seems to be originally produced for the Swedish market and are graded in mm Hg. Besides of these I also have modern high quality copies graded i mBar. It is a very pedagogical way to demonstrate that air pressure varies even on the hour basis ;)

I have a similar barograph, nr.23957, with RF monogram on the base plate. I purchased it 45 years ago at an auction for $50.
