Any info on US Divers Gulf first regulator

[Vq-1]

I'm having no luck finding any info on a US Divers Gulf first stage regulator. I'm only assuming it was available in Europe. Any info would be appreciated, thanks in advance.

Here's another pic. Interesting thing is that I did not know that US Divers made a first stage that was a swivel.

I have a USD Gulf 2nd stage that is the same as the Kirby Morgan Superflow 2nd.

Wow! Kirby Morgans look really awesome! I do admit, I have never heard of them. Didn't realize that they made those professional dive helmets, wow!
