In 1978 Colt Industries produced a limited number of this
weapon to celebrate the 60th anniversary of the Michigan
State Police. It came with a walnut fitted presentation case
with a scrolled plate affixed to the top with the following
inscription: "Michigan State Police 1917-1977. 60th Anniversary".
The Michigan State Police shield appears in the center of the plate.
This gun has never been fired.
Here are some additional photos of the gun and
