Electric Gyro Corp 1394T100-(5Y) turn coordinator. Purchased working form a gentleman who did an avionics upgrade. The testing I was able to do confirmed that it made normal sound, the flag went away when power was applied, and it reacted properly to tilting. No connector or documentation included. Can be returned within 30 days for any reason.
