Featured A bit of help with Worthpoint sale price, please?

A Short & Mason barograph sold on Worthpoint, but I can't see how long ago or the selling price. Would someone here be kind enough to have a look and let me know?

I have exactly the same model, only missing the glass cover and the ink bottle.

Thank you.
Frank

Thank you. Now I need to be on the lookout for an ink bottle.

 

Lovely old scientific piece Frank.Be nice if it still works-that's my kind of weather station.

 

Mine does still work, and is accurate over a long time as compared with another barometer. The clockwork mechanism give one rotation in seven days on one winding.
