This is a really good condition and working barograph dating from around 1920 although I haven't actually looked up the 6 digit design registration number 468791. It comes in a nice oak case of great colour and very well made. The usual French 8 day clock movement drives the drum and keeps good time for a mechanical time piece which runs for a full 8 days. It does not come with ink and I do not have any spare papers but I believe that these can be bought on line.
However, as you can see from my feedback I always give whatever after sales service I can. 12.75 wide by 6.5 inches deep by 7 inches high overall plus handle.
PLEASE NOTE, THIS WILL NEED ADJUSTING AND SETTING UP FOR YOUR LOCAL ALTITUDE AND BAROMETRIC IF YOU WANT ACCURATE READINGS FOR YOUR LOCALITY. It is simple to adjust and the adjusting knob is shown in the upper middle of the last photo.
