This sabre was likely made around 1935 to 1940 for an officer of the Republic of Cuba. The inscription Ejército Constitucional refers to the national army, who took this name in 1935. Interestingly, the inscription on the reverse was scrubbed off, possibly following a change of government.
This sword is in near pristine condition, with very nice and deep etchings. It is designed along the lines of German sabres of the same type and was made by Carl Eickorn.
This is a very rare sabre and I was not able to find any other example of a similar one.
