Thank you for the post about the Balco sub goggles, dmaziuk.
Next up is the Balco sub snorkel-mask with the product name "558".
This is a diving mask with full face coverage, a circular lens surrounded by a top screw retained metal rim, a stiff rubber skirt and a split adjustable head strap. Twin breathing tubes emerge from either side of the skirt, terminating in shut-off valves of the so-called "Gamma" type also used for Cressi snorkel-masks. So far as I am aware, the Balco sub 558 model can still be purchased. I have one in my collection, bought new from a Cypriot online retailer several years ago.
