Birth Date help for Model 66-1 please

[BIG DOG]

I picked up this 66-1 today.
Very nice looking and handling 6 shooter. It came with a Galco holster ans 3 speed, matching blue cardboard box and the bag of unused tools.It both pinned and recessed.
The serial number is 85K3XXX. Can any one help with the birth date?
Anyone else carry one of these Combat Magnums daily?
Thanks

1980 in the SCSW. Those stocks look great with the deep finger grooves.
Enjoy!

They make us all appear to be experts.
