Vertical speed gauge

Vertical speed gauge with paperwork Teledyne.

Vertical speed gauge in great condition, and includes paperwork and tag. The unit has been removed unserviceable, however from the tag this appears to be due to an instrument upgrade (in 2001) within the aircraft rather than a fault with the unit. 

The unit has not been tested and is therefore sold as seen, any  attempts to restore must be carried out by a suitable professional. The rear pinout is in good order.
