I picked this up Sunday at a local gun show along with a bag of K frame grips (round butt for some reason), and a holster.
It's a Model 66-2, made in 1985
It's got a polished smooth mark in front of the tiger guard on the left side, another couple polished smooth marks above the trigger on the right side, and a couple slightly boogered side plate screws, but is otherwise in excellent condition.
The trigger is superb in both DA and SA and it shot great at the range yesterday afternoon.
I just need to replace the Pachmayr grips....
