Lakediver sent several USD catalogs for me to scan......... CLICK HERE US DIVERS 1983CATALOG
There are several things in this catalog I do not remember from 1983......I was working at a Scubapro store but thought I was pretty aware of what was going on with other manufacturers ....With that aside I do not remember the big push to incorporate JM Cousteau into all the gear........Never heard of nor do I remember seeing a Royal Aqua Lung Supreme or Royal Regulator nor Royal Octopus.....There is also an Aquarius 2 that is very similar to the original. Neat stuff to see. Enjoy!
