Vintage Warren Controls Temperature Tracker

Description

Offered for sale is a vintage Warren Controls Temperature Tracking device.  The item is in good cosmetic condition but I have not been able to get it to start-up.  It is key-wound and works similar to a wind-up clock so the internal gears may need cleaned/lubed to get it working.  It also uses paper inserts for the dial that the transcriber marks during the week to show temperature changes over time.  The paper insert is not included.
