That first stage is a Scubapro Mk-2, which is a basic un-balanced piston regulator.
The mask has a simple downstream demand valve on the very top. You can see the demand valve lever in some of your pictures.
The glass is suspended around the perimeter by a single bellows or a single convolution of flexible rubber. This allows the entire glass viewing port to double as the demand valve diaphragm. Since it has a very large area, it has a huge mechanical advantage. It is a very easy breathing demand valve regulator.
You could breath into your nose or mouth, but most of the time it was best to seal your mouth around the horizontal tube. The exhaust is through that horizontal tube, out both sides.
I have only used this type of mask on a test dive (many years after it was produced) and I was impressed by its performance.
I actually own one of them, but the rubber is not in good shape and it is only useful as a display or show and tell.

Here are some picture showing some details.
You can see the demand lever here and the "mouth-piece".
You can see the exhaust ports here:

Hello Luis, first of all it is a pleasure to read you, I have been doing it here in the forum for a long time.
Thank you very much for the information, it seemed like a mk2 indeed.
Now I only think about getting one and putting a mk5 on it

Luis, without wanting to abuse your kindness, I have a question that has always intrigued me.
Why did Scubapro stop producing in the United States to come to Europe?
I understand it was all economy, but and the prestige of the U.S.A. flagship brand, U.S.A. manufacturing.
Its prices have not gone down and it is going very well for me that it is in Italy, but I do not understand it.
Atomic, for example, resists in the U.S.A, I would be talking with you for days.
If you come to Spain, contact me.
