Old Reg-help wi ID

This was my first reg, I bought it from a friend who bought it from a dive shop who were replacing their rental stuff. It has served me well since 1994/5. It now serves as my octo. It still works well, I've put over 150 dives on it but I am thinking of going Nitrox. I doubt this will work with it but I would love to know exactly the year and model for sentimental reasons once I retire it. Serial number is 257951. I haven't been able to find any images of it on the net.

In order to determine the model, please take the first/second stage to any authorized dealer and they will help you identify it as we do not have any serial # tracking to help you identify the unit. It looks like an older 3000 series and could be a a Brut, Magnum or Oasis.

Reguardless of the model, as long as you are sticking to rec (40% or less) nitrox it's a non issue.
