apologies for a slow reply, I’m normally very fit but perhaps age is catching up!
That is a monster of a console! It’s clearly a radio production console; we built them for a number of stations in the 1980s. It has a fortune in PPMs!
Not sure what those connectors are… the panel may not be original!! The connector types that we used were either ‘EDAC’ or ‘cinch’ and they are still available from RS and Farnell…. I do recognise that type and it’s odds on that they are still around today. 
On closer inspection… the panel does look original, but I certainly don’t have any info on pinouts. Suggest a hunt through the RS catalogue…. I have had a look in CPC and drawn a blank.
