Here is the PS/2151 Antillas con boya breathing tube from
1961:
Spanish: "
PS/2151. — ANTILLAS CON BOYA. — De iguales características que el PS/2129, pero provisto de una boya al final de la curvatura superior para impedir la entrada de agua al sumergirse".
Rough translation: "
PS/2151. — ANTILLAS WITH FLOAT (VALVE). — With the same characteristics as the PS/2129, but supplied with a float (valve) at the end of the upper bend to prevent the entry of water when submerged".
So the valved version of the PS/2129 that we reviewed at the weekend. The Antillas con boya lasted rather longer in production. This from
1962:
1964
Supposedly more comfortable than the conventional lugged mouthpiece, the oval biteplate on the snorkel mouthpiece is a bit clearer on the above image.
1966
The last appearance of the model.
So much for today's snorkels. Next time, at the weekend, we shall take a closer look at the Nemrod
Menorca and the PS/2155 Menorca de luxe breathing tubes. Until then, keep safe and stay well.
