Just thinking aloud here, have done some digging but currently at work and only have a few minutes… This line from Q drop:

SIG_con_MAR39sv3665BECD

The "sv" in the middle could be a separator, and when reversed: "vs"; as in verses…

Right side of the "sv" kind of reminds me of HEX, and Left side, well I'm not so sure. Perhaps a date March of '93, "con" meaning with, and GIS

Perhaps this is a bit of almond juice for the autists/diggers here.
