Manufactured in 1977 with standard markings and features as well as nearly full coverage factory floral scroll engraving with the "COLT ENG" marking under the left grip. The accompanying factory letter confirms the factory "D" engraving.

Excellent overall, retains 99% original blue finish with a few scattered light handling marks, some scattered dark spotting on the sides of the hammer, and a light cylinder drag line. The grips have only the slightest handling marks and sharp checkering. Mechanically excellent.
