Any info on this old regulator?

Looks like an old MK V first stage- since it has the main LP hose coming out of the end. The second stage might be called a 108 (?). When I did my Scubapro repair course out at the factory in 84' most people were using the 109's for their second stage- looks just like yours, but with an adjustable flow knob sticking out the end. The other hot second stage at the time was the AIR I. The metal second stage worked better than the AIR I for the cold water we dive in around here as they were less likely to freeze up and free-flow.
I'd take it in and have it overhauled. It was a decent reg back in the day and can be again. Expect to have to replace the internal rubber parts as part of the overhaul and you'll be all set.
I have a 30 year old Mares MK II that I was just using for tire inflation around the house and ended up grabbing it to use on a salvage job a couple summers ago. The reg still worked like a champ- although, it doesn't breath quite as easy as my newer Apeks TX50's. Still, for a 50' dive, in 40F degree water, with zero vis it worked great and I had the utmost confidence in it.

My dad said he had it serviced 8 years ago but the rubber does look less than youthful, and the mouth piece is completly gone but there easy enough to replace.
Thanks for the help.

Mark V /108. Good solid regulator and easy enough to service. Take it to a dealer and have it serviced. Not as good as some of the new regs on the market but a solid performer. It doesn't look well taken care of and a slight acid bath might clean up the chrome. Make sure the poppet and diaphram are replaced on the second stage and the piston is sharp on the first stage and the teflon disc is new. Not much goes wrong with them and the second stage can still be used as a safe second if you were to purchase a newer second stage. There are multiple ports on the first stage just for that reason.
I don't rinse my equipment but in your case......rinse in fresh water and let dry after diving.
After taking a second close up look at the photo, this regulator was in fact used as a safe second stage (back up). If it has a long hose on it (36" rings a bell but it's been years for me) and by your comment about the mouthpiece is missing and a close up look at your photo, that would be my guess. What happened to the other first stage? Probably a 109 that was sold with this combination with a screw adjustable spring on the second stage.

I always remember Scubapro putting orange rubber mouth pieces and exhaust tee's on their safe seconds and only used black rubber on their primary regs.
BTW: I believe it was Sam Itchakawa who ran me through my repair course when I was out at the factory back in 84'.

Agreed Jon, yes, they always left the factory with Orange.
I spent too much time in repair with Sam listening to his dive stories and on an occasion he went out on the "Scubapro" with us. My signature photo was taken by him on evening off Ship Rock. I don't know if he is still around but enjoyed his time immensely.
I was there in 84 and we probably passed not knowing each other.

Sam is still around I saw a post with him and Dr Miller a year ago on another site but I do not remember his user name at this time. Perhaps our friend Popgun knows and can PM you.
