3 sabres: officer 1821 and 1855 type and briquet.

The 1821 saber is in very poor condition, but it remains interesting for potentially salvaging the hilt and blade, or for theatrical fencing after a thorough cleaning.
The 1845/1855 pattern saber is simply dirty and needs a good cleaning/stripping. After treatment, it will be suitable for a collection or for use in fencing. The model is inexpensive, so it's not rare. Don't worry about damaging a rare item; others will follow. This saber was used from 1845 until World War II. Once cleaned, it will be quite impressive.
The briquet is more surprising; the blade is a wreck, but the hilt is of an unusual design, hollow, and appears to have been made in two parts.
Most importantly, it is marked with numerous inscriptions in large characters: 1814 and IBA.v. L.N.28.
28th Line Infantry Regiment???? Price reflects the condition.
