SCUBAPRO Regulator Overhauled diving regulator Only a few specs USED

I bought it around 2008 and used only a few until 2010.

It was stored in a warehouse from 2010 to 2021.

I put it out for overhaul and it became shiny

It's been about 13 years, but I think it's still usable because it's been overhauled because it's been overhauled.
