Connector Identification/Equivalient

[Buriedcode]

Hi,

I am trying to find a suitable replacement connector in the picture attached (the green thing).

The closest I can find is a Monacor CN-11J:

Clones of which I have ordered from CPC:

Now, the important parameters like pitch, pin size and distance between mounting holes are the same.  But the panel cutout has different dimensions, and the original has a greater depth and smaller recess - so original plugs used on the replacement (CN-11J) are far from a snug fit.  Whilst I'm fairly sure the CN-11J is a suitable substitute I was wondering if anyone had seen the original connector anywhere?  As its just a two pole connector, search terms are far too generic, and an image search hasn't provided any results.  If it helps I have only seen the original connectors in that lime green colour.

I have to replace a fair few, so widening the panel cutout isn't ideal, but its only 2mm each way.
