Directional Gyro, Italian Royal Air Force (Regia Aeronautica Italiana), Filotechnica Sperry

This is an exceptional example of a WWII-era Giroscopio Direzionale, made by Filotecnica Sperry in Milano Italy, was used in aircraft of the Regia Aeronautical Italiana.  This was likely made by Filotecnica under license from Sperry, but the precise history of the manufacturing source is unclear.  On the dial there is text which reads "Scade Radium 15-9-43", which essentially translates to Radium Expires 15 Sep 1943.  Therefore the instrument was likely made several years earlier.  It is clearly experienced but is in fine condition as a rare collectible given its age.
