Spanish Utility Model # 27,560 - Triplex?

Spanish Utility Model 27,560 - Triplex main image

This 1951 Spanish Utility Model depicts a derailleur that is almost a carbon copy of the 1949 Huret Compétition. It is credited to Pedro Idigoras Eguén - a name that is not familiar to me. I have suggested that this is a Triplex design because this Utility Model is referred to in a proprietorial way in Spanish Utility Model # 66,251, which is credited to Antonio Bascarán Rementeria, the owner of Triplex.
