Please help on 1796 HC sword marks

[Jim McDougall]

Manolo, it is indeed surprising the numbers of British weapons that ended up in Spain during this period. In discussions over the years concerning the so called 'Berber' sabres that became associated with Spanish Morocco via Mr. Tirri's well known book, and now seem more likely to be from the 'Spanish Main' from Cuba to South America and Mexico's gulf coast....these seem almost invariably mounted with British M1796 light cavalry blades with tips dramatically profiled.
I have seen other South American swords of mid 19th century also with British blades of the Napoleonic period.

These markings are on the langet of a M1796 light cavalry sabre, and I am wondering if they might be associated with Spanish markings:
