Late 18th Century Or 1stempire Sapper Saber With Enormous Blade

This sapper's saber has a blade that is really over the usual size. This blade can be dated to the last quarter of the 18th century. It has a shape that can be found, for instance, mounted on the sabers of the Corsican Legion, or on certain navy sabers, but it is oversized.
The cast brass hilt represents a crowing rooster's head and a cross guard  with lion heads. The crowing rooster should not be surprising since this motif appears from the end of the Ancien Régime, for example on the sabers of the King's Constitutional Guard.
This saber can reasonably be dated to the end of the 18th century, or the beginning of the Empire. Sapper's sabers have many variations, and it would be unrealistic to try to date them precisely, since they continued to be worn for a very long time.
BLADE: This is a very strong blade, which has a large hollow section on each side. The back is flat, we find at the heel the motif called the "grape branch" which indicates a manufacture from Solingen. Counter edge on the last 26 cm near the tip. The tip ends in a "carp tongue"
At the heel of the blade, floral cartouche and on the first third of each face, decoration of plant interlacing typical of the 18th century. Length of the blade = 62 cm, width at the heel = 6 cm, thickness at the heel 11 mm
CROSS GUARD:   cross with straight quillons which end in lion heads. Large lion head on each face in the middle of the cross. It is cast separately from the rest of the hilt.
GRIP: it is made of faceted brass, and ends with a crowing rooster's head, tongue stuck to the mandible.
SCABBARD: it is made of wood covered with leather with mouth of the scabbard and brass chape with sides cut into braces. Brass dart on the chape.
This saber looks great, its authenticity is beyond doubt, and its very unusual blade makes it an exception, reinforcing its interest.
