This was the standard French Cavalry Officer's Saber in in the late 1800's to early 1900's. It is very similar to the French Model 1882 Officer's Sword but is brass-hilted instead of nickel plate; additionally, the blade is curved whereas the M1882 is straight.

Manufactured at the Klingenthal arsenal in France and so marked on the blade back-edge near the hilt (see images).
