I believe the 1898 SAW 'relic' may be a Spanish naval 'contact mine', invented around 1885, by Spanish Navy Capitan Joaquin Bustamante.

Capitan Bustamante died July 1, 1898, during the land battle for Santiago de Cuba.

Where is this 'relic' located?

(I suspect those curved 'pivoting arms', on the "relic", are a model variation and were welded, at a later date, to prevent vandalism.

My hunch is that, they are a sort of 'trigger-guard', to prevent accidental detonation by smaller civilian watercraft & fishing boats.

They look like they stayed in the 'up' position, but, would slide and collapse, if hit by something "Big").
