This modern barograph by Casella Ltd. is the same pattern which sits on the mantlepiece in Doc Martin's consulting room in the later episodes of the well-loved TV series. The workings of the instrument are a most interesting advanced configuration from the traditional lever system between the diaphgram and pen arm and surely appeal to those who are looking for an accurate recording instrument encompassing a new and innovative design. The clockwork movement and drum take standard charts and a selection will be included along with a fresh bottle of recording ink. The case looks to be finished in polished mahogany with bevelled glass to the lift-off lid and the chart drawer to the base contains a copy of the origal instruction manual.
A brass presentation plaque is included which can be fitted to the front and centre of the chart drawer, where there is evidence of an earlier small engraved plaque, now removed. 
370mm wide x 230mmhigh x 235mm deep.
