Need help IDing a 12.7mm 2-pin round connector...

• Hi,
  
  I'm trying to find a mating plug for the power connector on a data radio (a Maxon DM200; power cable part number ).
  
  The radio-side connector is male (has pins) -- so the mating cable-side connector would have to be female.
  
  The external thread diameter at the radio side is 12.7mm, with a threaded length of only 3.5mm.
  
  There are two pins. The left pin has a diameter of 1.5mm, while the right has a diameter of 2mm. This is the only keying on the connector - the pin size difference.
  The pins are approx. 4mm centre-to-centre.
  
  
  I've found a picture of the connector (plugged into the radio), which I've attached.
  
  Does anyone recognise this thing?
  
  
  Thanks
  Phil.
  
  (EDIT 2018-09-06 to add photo of the front of the connector, oops)

• How do you expect us to identify the thing if we can't even see the pins? A better picture would help greatly.

• Definitely need a picture of the face of the connector to really be of any help...
  
  But from what is shown it kind of looks like something along these lines:

• Oops! I knew I'd forgotten to attach something!
  
  Photo of the face of the connector attached. You can see that one pin is slightly smaller.
  
  (The other connector is the TNC antenna connector)
  
  
  I've looked at the GX16, but it's polarised with a notch, like a DIN plug. This strange thing seems to use the pin sizes for keying, and possibly the pin position (they're slightly off-centre in the "up-down" direction)

• I've got some more (better!) photos of the connector.
  
  All the plastic parts are green.
  
  The panel hole appears to be 12mm diameter, with a rubber or foam washer between the connector surround and the panel. The mounting nut is one of those round ones which needs a pin spanner to remove. A bit like the ones Lumberg use on their locking DIN connectors. Pins are numbered on the back.
  
  Oh, and it has a logo on it. A "W" in a circle?

• Right then, I reckon this mystery's solved (or solved enough for me).
  
  Talked to the company who took over support for the radio manufacturer last night. It's apparently a custom made connector (!) and the cables are £50 each, plus postage, plus VAT, with a several week lead time!
  
  So in the true spirit of bodgery, I stripped the thing to bits and replaced the connector with a GX12-2 "aviation connector". Added fresh cable (mmm, silicone wire!) and a PowerPole and now I have a working Mobitex radio to play with!
