Question Which Scubapro first stage is this?

[keeblerelf]

Hey everyone. Ive got a scubapro first stage that doesnt have the model number stamped on it. I can't seem to figure out which model it is and I'm hoping someone here might be able to help me out! There are four LP ports on a swivel and two HP ports. Thanks!

Looks like a Mk18.

Thanks! I think I googled every MK model except 18

Five lp ports on the swivel. (one is on the end of the turret. )
I have service kits. PM me if you are interested.
