This "fantasie" antique example of the French 1882 style Infantry Officers sword has an unusual, non-regulation blade. It is hollow ground triangular in cross-section, and is known as a Préval blade, named after General Claude Antoine de Préval, who trialed a similar style of blade in the 1830s as he believed it made sense from a cavalry perspective, being light, strong and very stiff.
The guard is also non-regulation. It is made of steel, instead of the standard German Silver (a white bronze alloy). It also has reinforcing ribs, unlike the regulation variant. It also has 1 extra outer sidebar and two inner bars.
It is marked Coulaux & cie, Klingenthal.
This style of Saumur hilt, combined with various unique blades, were often used by Zouave and Chasseur d' Afrique regiments from around 1855 onwards, and formed the basis on which the 1882 hilt was eventually built.

Overall, each side of the blade took 6 applications of gel. Each gel layer must react for 1 to 2 hours. The entire process took many hours - including the various cleaning steps that occur between gel applications - which will be included in the full video.

**Ethics Considerations:**
This particular antique was corroded to a substantial extent and its structural integrity was threatened, as corrosion products developing in the crack of the blade can worsen the crack and potentially fully break the blade.
Conservation and restoration allowed for stabilisation of artefact as well as for the underlying construction method of the steel to be respectfully revealed and appreciated by addressing the deterioration, and also allowed for preservation of the object for the future.
Care was taken to ensure no undue losses were incurred, and the work was conducted only to a degree where the object was stable, and free of active corrosion products.
