A very rare WW1 French Spad altimeter by the renowned makers Naudet & Co, Paris.

The instrument is in excellent original condition and retains the outer leather case. When in use it was fixed within a sprung cradle to reduce vibration from the engine.

It responds well to atmospheric pressure variations and can be set to the correct altitude.

This altimeter would make an excellent addition to any early aeronautical collection.
