Looks like a MK2.

It is a MK-2, and it isn't old...

Unbalanced piston first stage. Simple and robust.

It is my "stranded on a desert island" first stage choice....

I use them on my pony bottles, redundant supply for ice diving, and for DECO bottles.

Thanks! My dive shop owner wasn't sure.

Any suggestions on a good match for a 2nd stage for a solid deco setup?

Yep, newer MK-2.....I would wonder about a LDS that does not know what it is, they are very common and have been around for many years. You can pair pretty much any second stage with it, a 109 would be perfect.It's not fancy but a rock solid reg.

maybe match it with a modern r series?

Before I read @herman post, I was also wondering about the LDS owner. He or she most be new to diving.

This 1st stage has changed a little bit since it was introduced around 1965 or so. You can now get it in DIN and they added that black rubber open boot.

Turns out the newest EVO’s have a replicable orifice! Now they should last double forever.
