Spanish Utility Model # 39,933

Spanish Utility Model 39,933 - Triplex main image

This is a registration for a ‘Utility Model’ - a kind of patent-lite. I included it because it shows Triplex as actively developing derailleurs in the 1950s, and because I like the sound of the word ‘deslizador’. This seems to translate as ‘powerboat’, but I suspect that in this context it means ‘derailleur’ or even, regrettably, ‘front derailleur’.
