I recently acquired a 1st stage regulator from a local seller from whom I purchased a tank. He didn't remember much about it, research shows it to be a vintage Scuba Pro MK5 (two LP ports) with a very nicely done DIN connector in nice shape. IP holds steady at 140 PSI,[-] but I do hear hissing from it so there is a small leak[/-]. Strike the leak note. The two fittings on the LP side are different sizes. ScubaPro must have had a better idea about how to build a regulator 
I want to use this on an Argon bottle, and I'm told it is gross overkill for that purpose. I'd like to swap for some sort of DIN 1st stage (balanced or unbalanced, reasonably recently serviced) with a button pressure gauge.
Any interest?
