"D" is the fork steerer tube length, and would be correct for a 60cm frame. There should be three digits in front of the D, and it is the seat tube length from the center of the crank spindle to the top of the seat tube in millimeters. If it's a 60cm frame, that would be 600D...
"W" indicates the frame was made at Schwinn's Paramount Design Group (PDG) facility in Waterford, Wisconsin.
You've got the M86051 decoded correctly. Since it was a December build, the specs are likely 1987 model year.
