I recently found this sabre in 'sleeper' condition. It matches criteria for a French AN XI model but there again similar sabres were made all over for the rest of the century.
It has the (maker's?) name PRATIER on the ricasso, a partially visible poincon on the other side - possibly the same 'B' in an oval - which is stamped on the guard. The hilt is stamped 20 and also with V.1837. The latter stamp seems more recent than the rest.
There are also numbers/letters partially showing where the blade meets the hilt - I cannot really get to them without disturbing the remains of the 'cravate de drape rouge'
I would be grateful for suggestions...
