Electrical / Data Connector Guru?

My Google skills have let me down this time.  Just bought a used TraqMate Classic data system for next to nothing (yes, I understand its old, I can get newer fancier systems).  Its missing the extension cable between the screen unit and data unit.  The manual labels it as a DIN extension cable, but it's not a standard DIN size.  It's 6 pin, round configuration, but in what I would describe as a clover leaf configuration.  It is self locking.  You have to pull back the "sheath" on the female connector to release it.  I'd be shocked if this small company (long since out of business) created custom cables, with a one-off pin connector.

Picture attached?  Anyone know what this connector is called?

Thanks!

Looks like it's a Hirose circular push/pull connector:

It certainly looks like we have a winner and that would explain the HRS stamped into the plastic.  It also answers the debate on Is that a 5, or an S with the misses (apparently I was right) :-)  Thanks so much for the help!
