A Disconnecter projecting from the band of the instrument, opposite the fan-wheel, serves to throw the mechanism out of gear, and arrest its action when required. The instrument is packed, with the usual Universal jointed socket holder, in a neat deal box about four inches square. It comes complete with instructions, in its original box, together with a fitting for attaching to the base. Complete and all in very good original condition.
Mechanical everything is working correctly and the dial registers as the fan-wheel rotates. This is a very delicate mechanical instrument and care should be taken to never touch the rotating fan blades.
