Vintage Hythergraph Recorder Humidity Air Temperature Julien P Friez Steampunk

Description

From the family business estate.  This is for a vintage Julien Friez & Sons Hythergraph, recording relative humidity and air temperature.  I do not believe this is functional so this is listed for display or collection purposes only.
A great addition for the collector or for that unusual display.  Stored in a dry and smoke-free environment.  Please review the pictures and if you have any questions, please ask.  Sold as-is with no returns.
