A set of three illustrations with the designs of the Turret Coles, made in 1980 by Mr. Gonzalo Maguiņa, probably copied on the original designs made by British Captain Cowper Coles. The first one, above, shows very clearly the round platform, the mechanism that allowed the rotation of the tower, the iron and teak-wood armor, and the two 500 Armstrong guns. Below, a transversal and longitudinal view of the tower (Drawings, courtesy Mr. Gonzalo Maguiņa).
