ID an old DIN first stage

[Jordi]

My first thread on this site, where I constantly find interesting info.
Recently purchased a bunch of old gear and I am trying to restore some of it. The one in the picture looks like an OCEANIC PX2 but it is not, I am guessing a bit older but I have not been able to identify it further. There are plenty of similar ones in ebay but they are not ID correctly.
As you can see the first stage is only partly assembled but all the parts are there. The PX2 (balanced piston) service manual was useful in disassembling most of it but the body of the first stage is definitely different.
Thanks in advance

Scuba pro Mk5.

The DIN connection is pretty rare, very few MK 5's had it, or at least have survived into modern times.

Looks like a mk5 to me.

Great help guys. An MK5 it is. Could not find a full service manual for it but at least a parts description so I am set to go. Much appreciated.
