A rare WW1 period Jaeger Type AM (Aviation Militaire) aircraft tachometer.
Circa - 1916 / 17.
As fitted to a variety of French aircraft of the period.
In good complete original condition with clear dial, needle and bevelled glass.
There are some light scratches to the glass.
The instrument is in working order with the needle returning to zero, and having
a quality chronometric mechanism means the 'drive' will operate both ways.
It also retains all four fixing 'lugs' these are often damaged or missing.
