Fell in love with these more than thirty years ago and finally was in a position where they were available, in great condition, and finances were not an issue. These were made in 1967 and 1968 to commemorate the fiftieth anniversary of the end of WW1. These two are the Battle of Belleau Wood (1968) and Battle of Chateau Thierry (1967) models. The other two commemorate the Battle of Meuse-Argonne and the Second Battle of the Marne and were both offered in 1969.
Not really clones of the WW1 pistols other than the lack of cuts around the trigger guard, thumb safety, and the smooth flat mainspring housing. The rest of the parts are regular pre-Series '70 Commercial Colt parts. The gold-filled engraving and high-polish finish also were nothing like the original 1911. As such, collectors never took to them, so prices are lower than regular pre-Series '70 examples demand. They are all steel and walnut with pretty decent fit and great finish.
Still looking for the other two in the set with the same serial number.
