Rivkin, thanks very much for the kind reference
very much appreciated.
This sabre is apparantly one of the many variations of branched guard examples favored by Mexican officers after the independance from Spain of Mexico in 1821. There were considerable stockpiles of these familiar three fuller dragoon blades (many disagree with that term, but it is often used as seen in the Chamberlain reference) in Mexico for long into the 19th c.
These are considered of the M1769 Spanish troopers pattern (Chamberlain, op.cit.).
The eagle does of course appear to be a variation of the Mexican national emblem, and there were numerous variations, unclear as to the progression of detail such as the wing tips. It should be noted that these sabres were used very late into the 19th century, and often favored by the ersatz police forces known as 'rurales' during the Diaz regime.
The swords of Mexico and early colonial New Spain are a personal favorite, and represent a colorful heritage that is often very much missing in many, if not most, studies of antique edged weapons.
Very nice example !!!
All best regards,
Jim
